Air travel gives me the time to do pleasure reading, especially if I'm stuck in a middle or aisle seat. I'm baffled by people who can seemingly sit for two hours on an airplane staring off into space. Oh sure, they'll pick up the airline magazine and quickly thumb through. A few people pull out their laptops and catch up on work or play a game. I seldom pull out the laptop except on longer cross-country flights, which for me are rare (last one was February 2004 to the Carolinas, into Charlotte and out Raleigh-Durham). Most of my air travel is western US, with flights under three hours. I'm usually not very chatty and most other people aren't either. Every once in awhile I sit next to an interesting chatterbox. Really, I prefer to read or stare out the window.
So what am I reading now? I just finished up "A World Transformed - Firsthand Accounts of California Before the Gold Rush" edited by Joshua Paddison. It's a collection of writings from early California explorers and adventurers like Juan Crespi, George Vancouver, and Richard Henry Dana, with Dana being the most interesting. I'm reading now "Bear Flag Rising - The Conquest of California, 1846" by Dale L. Walker. This book is about that short timeframe when Americans began streaming into California as the vangaurd of manifest destiny and Mexico lost control of her far off and neglected territory. The book has a great cast of real characters, the most infamous of course was John Charles Fremont.
I have been reading these books mostly because of my frequent travels to my native state. Sure, I picked up a lot of California history just growing up and going to school there. The history is worth refreshing and expanding, especially the colorful history of California. I so love history.

A Couple Days Off
I'm taking a couple days off at the end of the week to recharge. This has been an almost non-stop busy year and I haven't taken much vacation time. The boys are off school for these two days and it's youngest sons birthday, turning 11. He's having some friends over Saturday for a sleepover, where they will "Destroy all Humans" and other fun electronic games.
I managed to push my Renton Phase I, the Silicon Valley parking lot Phase I, and the noise assessment reports out the door. We are also working on a much larger parcel in Silicon Valley that we're already into Phase II subsurface investigation for the usual suspects - gas stations and dry cleaners. I added my site visit findings to the OC Phase I report and sent it down to my colleague in Irvine.
I prepared a proposal for some additional contamination characterization at a Seattle Central District redevelopment project and we got the go-ahead for that. Now I need to schedule the drilling and find staff.
I prepared a proposal for remedial action services for a redevelopment site near downtown Tacoma to address lead contamination in surface soil. When old houses are demolished they usually leave behind traces of lead paint and that's what happened here. This is a soup-to-nuts project - workplan, excavation oversight, sampling, and closure report. We work with the Washington State Department of Ecology through their Voluntary Cleanup Program. We submit a Workplan that spells out how the lead soil will be removed, how and where we'll collect soil samples for analysis, and what criteria we'll use to confirm the site is cleaned up. I did a similar site just two blocks up the hill and obtained a "no further action" determination from Ecology. This new project is essentially the same as the one I did last year.

The OC in One Day
I flew down to John Wayne early Monday morning catching a 6:40 am flight out of SeaTac on Alaska. The line was long at Qdoba so I didn't have time to grab one of their decent breakfast burritos. The Starbucks line was long, too, and I usually try to avoid the homogeneity of Starbucks. So I stopped at Dilettante Chocolates & Mocha Café, across from Starbucks in Pacific Marketplace. I ordered my usual 20-oozer latte and a cranberry scone. The scone was soft and so unsconely uncrumbly. It sucked, but I ate it anyway.
The plane was full and I had a middle seat. At least on Southwest, I can usually score my coveted window seat 20F (or 20A) by checking in on-line and scoring the "A" group boarding pass. At least I got in a lot of pleasure reading over the two hour plus plane ride.
The last time I flew into John Wayne was a few years ago (I can't remember the exact year). It must have been not too long after 9/11 because I recall National Guardsman patrolling the terminal with M-16s.
The site I was visiting for this project was a large industrial/warehouse building located in northern Orange County. It was totally vacant but in its former life had been a carpet factory and most recently occupied by an aerospace company. Other consultants were running around the place, some I knew well, others I was meeting for the first time. I spent the better part of the day working my way around the property from the roof, to the inside, and around the outside. I collected samples of building materials for asbestos analysis, looked for indications of mold growth, stains, spills, and other indications of environmental problems. The place was swiss-cheesed with soil borings, some were hollow-stem auger borings and others were direct-push probe borings. Someone had characterized the site very well. But I had none of the data in hand.
I finally wrapped up my site work around 4:30 pm, finishing with a review and drive around of the surrounding properties. I didn't have enough time to review building permits at the city. I had wanted to finish the day with a walk around Upper Newport Bay, but the days are too short this time of year and when the sun goes down in these southerly southern California latitudes it gets dark quickly. Picture the sun diving into a pool. In Seattle, the sun dives into the pool at a low angle, not quite a belly flop but more a racing dive. In southern California, the sun dives almost straight down.
I was starving having milked that soggy scone for all it was worth for the whole day. I decided to head over to Costa Mesa to see if that sandwich place was still there at 17th and Orange that I used to stop at after a day at the beach (Newport Beach). Sadly it's a dry cleaner now. But Chester Drawers was still there tucked in the corner of that neighborhood shopping center, a great little spot with beer, burgers, dancing, and shuffleboard. The clientele going in was young and beautiful, just like it was 20 years ago when I would hang out there with my Orange County friends. I'm not so young and beautiful anymore, so I grabbed a sandwich from a nearby Panera.
I checked in early for my non-stop flight home to Seattle, which as it turned out was canceled. The ticket agent was having a bad day and so it made me have a bad day. Being nice comes easy for me and it usually results in reciprocating niceness. When people are not nice I can be just as not nice or even more so. Not getting much help from the Miss Not Nice, I went over to another to another ticket agent who was very nice and pleasant, who booked me on a flight stopping in Oakland then on to Seattle.
I had a window seat but it was already nighttime, which did make for beautiful city light views. I sat next to a father and his five year old daughter. She was a delightful and intelligent child. They were returning from a trip to Disneyland.
I finally walked in through the door at home around 12:30 am. I scrounged for a little snack food, crawled into bed, kissed the wife, rolled over and fell asleep.

Parkfield Junction - California Dreamin' - Part VI
Upcoming Events - The OC
I fly down to The OC Monday morning catching a very early 6:40 am flight into John Wayne. I'm picking up a Phase I site visit of a warehouse building in north Orange County for our favorite client. My Irvine office colleague who would normally do this is buried in work. I fly back out the same evening, getting back into SeaTac at 11:14 pm. It looks to be a long day with plenty of time to catch up on my pleasure reading. I'm not one to unfold the laptop on the plane and work. I read or look out the window. It's likely I'll have time for a walk around Upper Newport Bay before I fly out - a great birding spot and close to the airport.
We completed a one-day internal training course last week on the new ASTM E 1527-05 standard practice, updated for the new All Appropriate Inquiry (AAI) rules coming out. I was one of the course instructors. I had a fun time doing it.
I have some outstanding reports to work on also - the Silicon Valley parking lot Phase I, a workplace noise assessment report, and a demolition-level asbestos survey report I did of a building undergoing interior renovations for a Microsoft move-in. Jeez, I wear a few hats.
The noise survey was interesting. I hung noise dosimeters on two employees and spent the rest of the day walking around measuring noise levels of different worker tasks using a hand-held sound level meter. Now the report is way overdue. Ugh!
I have a soil and groundwater investigation coming up in southern Oregon. It's for a national client buying a neighboring property at one of their facilities so they can expand. This is an interesting site with interesting problems. More on that later when it comes up. I have one of my Portland colleagues pegged for the field work.

The Best Laid Plans
Most of the soil and groundwater results came in for our Phase II project down in Silicon Valley. All looked initially good. We had some low level hits of diesel and motor oil range petroleum hydrocarbons in the groundwater, but no VOC hits in soil or groundwater. This is a bit unusual. Why no VOC or gasoline hits? You always expect some VOCs with a petroleum release. On face value this looked like a manageable problem - long term groundwater monitoring at worst was what I was seeing. I was still troubled by the source of the contamination. Where could these low level petroleum hits be coming from? Our investigation was really just a set of pin pricks into the ground. A potential source could lie under the buildings, which we could not access.
The other concern was we didn't yet have the parking lot results. They went to the lab late Friday. When those remaining results came in late Tuesday it was a shocker - big diesel and motor oil petroleum hits in groundwater. Again, nothing in soil and no VOC hits. The source was likely off site somewhere and potentially on the adjoining property that we initially investigated earlier in the week. We had no way to conclusively determine groundwater flow direction at this point. We had a notion of groundwater flow direction. However, below-ground parking garages were located on the neighboring properties. If these garages have sump pumps to keep groundwater out, then the pumping could locally influence groundwater flow direction.
Now we just have to wait and see where this goes next. It's in the hands of the buyer and seller, their attorneys, the lenders, and the insurance people.

Fall in Skagit County
We stopped at Tulip Town to buy bulbs. The best, biggest, and choicest bulbs are had right here from the grower.
We finished the day at the Skagit River Brewery for dinner and beers. Quality time with my folks who aren't getting any younger.

Pleasant Friday
I had a field day out of the office on Friday doing a site visit at two office parks in Renton. This was for a new client referred to us by a property condition consultant we cross paths with often. Typical site visit it was with a number of consultants running around the properties, most I've known for years. The tenants were all nice. The weather was gorgeous, a clear autumn day. It was a perfect way to end the week.

My Back Pages
I dropped the car off for an oil change at Toyota - every fourth change free. Yeah, you change your own oil, I know. Well I've changed a ton of oil and it doesn't get any more pleasant. I take advantage of the time and go for a long walk, snap a few photos of things that catch my interest. I strolled into the supermarket espresso place and ordered up a 20 ozer latte. The Byrds "My Back Pages" was playing. Man I love that song, written by Bob Dylan. I found a You Tube video from Bob Dylan's 30th anniversary tour, with Roger McGuinn leading things off accompanied by Eric Clapton, George Harrison, Tom Petty, and Neil Young.
Crimson flames tied through my ears
Rollin' high and mighty traps
Pounced with fire on flaming roads
Using ideas as my maps
"We'll meet on edges, soon," said I
Proud 'neath heated brow
Ah, but I was so much older then
I'm younger than that now.
Half-cracked prejudice leaped forth
"Rip down all hate," I screamed
Lies that life is black and white
Spoke from my skull, I dreamed
Romantic facts of musketeers
Foundationed deep, somehow
Ah, but I was so much older then
I'm younger than that now.
Girls' faces formed the forward path
From phony jealousy
To memorizing politics
Of ancient history
Flung down by corpse evangelists
Unthought of, though, somehow
Ah, but I was so much older then
I'm younger than that now.
A self-ordained professor's tongue
Too serious to fool
Spouted out that liberty
Is just equality in school
"Equality," I spoke the word
As if a wedding vow
Ah, but I was so much older then
I'm younger than that now.
In a soldier's stance, I aimed my hand
At the mongrel dogs who teach
Fearing not that I'd become my enemy
In the instant that I preach
My existence led by confusion boats
Mutiny from stern to bow
Ah, but I was so much older then
I'm younger than that now.
Yes, my guard stood hard when abstract threats
Too noble to neglect
Deceived me into thinking
I had something to protect
Good and bad, I define these terms
Quite clear, no doubt, somehow
Ah, but I was so much older then
I'm younger than that now.

Added Scope
All was going well down in Sunnyvale, albeit a little slow. A number of factors were slowing us down. We had to increase our target depth beyond 20 feet to intercept and collect groundwater samples from about 28 to 32 feet. We were hand augering the first 5 feet to clear utilities. We encountered a layer of gravel that collapsed into the hole each time we tripped out. Gravel can also have a camming affect on the rods and core barrel that can make it hard to pull them out of the the hole.
Our client called late in the afternoon and to let us know that they were also buying an adjoining parking lot that reportedly had a gas station. I quickly checked Sanborn Maps and found no gas station, but I did find that the lot had a truck repair facility in the 1940s and a print shop in the 1950s. Bad enough. We now needed to investigate soil and groundwater quality on this lot. The downside is we couldn't start for another two days. The one-call utility notification requires 48 hours before you can start drilling. This gives all the underground utilities time to mark the locations of their buried utilities. Hitting underground utilities can ruin your day and maybe get someone injured or killed.
I got the wheels in motion. I called the one-call underground notification system. I called the drilling company and fortunately they had Friday open, the soonest we could start after the 48 hour waiting period. I called our field geologist to mark out the new locations in white marking paint and to have her prepare for Friday. I love it when a plan falls apart and then comes back together nicely in a new form.

On to Phase II
The preliminary information we gathered on the Silicon Valley site revealed that the site historically had a dry cleaner tenant and, before the development of the existing buildings in the late 1960s, had two gas stations located on the property during the 1940s and 1950s. This information came from a prior Phase I report provided to us when we started the project. Other corroborating sources we looked at were Sanborn Maps and old city directories. Polk's and Haines directories are the common ones we find. You can find them in your local library.
The thing about dry cleaners is that they commonly use a chemical called tetrachlorothylene, synonymously known as perchloroethylene - PCE for short, or simply "perc." PCE is a chlorinated solvent that can adversely affect health with enough exposure, typically through inhalation or direct contact in an occupational setting. PCE is also a carcinogen. Usually dry cleaner sites that have been around a number of years have caused some PCE contamination to soil and even groundwater. Once it gets into groundwater, it's a bitch to cleanup. PCE gets into the ground a number of ways, usually through the mishandling of the chemical, chemical waste, and by dumping down the drain, storm drain, or out behind the store. PCE can find its way through a crack or expansion joint in the floor slab and leach out from a sewer line. Finding a dry cleaner during the Phase I assessment is almost an automatic Phase II subsurface investigation. Or it can just kill the deal.
Gas stations store their fuel supply in underground storage tanks. These tanks and the related piping have leaked more often than not at old gas station sites. Old gas stations also may have had auto service with hydraulic hoists in the service bays. The below ground mechanisms can leak hydraulic oil. Used oil is often stored in underground tanks. Solvents may have been used to clean parts. Gas stations, as you can see, have many potential sources for contamination to get into the ground. Gasoline, diesel, oil, and, in some cases, solvents are the potential contaminants.
Compared to PCE, petroleum contamination is relatively easy to chase. It usually smells and petroleum contaminated soil is usually discolored. Petroleum products float on water such that when a release of say gasoline or diesel filters down through the soil and encounters the water table it flattens out and floats. Of course, some fraction also dissolves into the groundwater. PCE, on the other hand, is volatile and the vapors travel along preferential pathways through the soil such as sandy zones, utility trenches, and under pavement. It is not obvious by smell or color in soil at trace but still hazardous concentrations. We use a hand-held organic vapor monitor to screen soil for PCE and other solvents. PCE is also heavier than water so it sinks rather than floats in groundwater. PCE is nasty stuff.
Based on these findings, I put together a scope and budget to sample and analyze soil and groundwater samples at the former dry cleaner and two gas station locations. We will use direct-push probe methods ("Geoprobe"). Direct push probing is basically driving a hollow core barrel into the soil and retrieving a core sample of soil. When we hit groundwater, we will collect a groundwater sample using a number of methods. The most basic method is to drop a slotted 3/4 inch PVC casing down into the probe hole and pump out the sample. Another method is to drive a hydropunch to the desired sampling depth and pump out a water sample. A hydropunch is a stainless steel well screen with a retractable sleeve.
As of today, we completed two probe borings. I had selected a target depth of 20 feet, expecting we'd encounter groundwater before 20 feet. I got a call from the young geologist in the field "20 feet and still no water." I told her to go another 10 feet and call back. As it turns out we hit groundwater at 28 feet.
No signs of contamination, but we'll see what the laboratory finds in the samples. We're doing a 24-hour turnaround, which is extremely fast and pricey. But the client needs results quick so they can make a decision on purchasing the property. Real estate transactions have become fast-paced, almost too fast-paced.

Silicon Valley Phase I
Monday and Tuesday of this week found me in Silicon Valley doing that Phase I project. I met one of my colleagues from our Sacramento office who came out to lend a hand. She's a young woman who impressed me with her initiative and intelligence. Our company hires some remarkable young people. We spent the day going through the property. I had budgeted two days for two people. But toward the end of the day I realized that I could wrap up the field work the following day by myself. With that I dispatched my colleague to head back to Sacramento. She was quite happy to be heading back home, being a newlywed with a new house and working on her Master's thesis.
Tuesday I met with the roofing consultant and two roofers to run around the roofs shagging roof core samples for asbestos analysis. The roofing consultant is a friend who I see on all these jobs we do for this client. He had just returned from Cabo and so we told our favorite Baja stories. I probably wouldn't recognize Cabo from when I was last there in the late 1980s. Even the barren beaches of Todos Santos are being developed.
We were joined later in the morning by the property condition consultant, another friend seen on these jobs. I joined the PCA consultant for a two beer lunch at the Firehouse Brewery. After that, I skipped over to the library to review city directories, a tedious task made more efficient with a digital camera.
I packed up and caught the 8:30 pm flight from SJC to SEA. I walked into the house about 11:40. My wife had made a delicious apple cake that made the perfect midnight snack.
Tuesday I met with the roofing consultant and two roofers to run around the roofs shagging roof core samples for asbestos analysis. The roofing consultant is a friend who I see on all these jobs we do for this client. He had just returned from Cabo and so we told our favorite Baja stories. I probably wouldn't recognize Cabo from when I was last there in the late 1980s. Even the barren beaches of Todos Santos are being developed.
We were joined later in the morning by the property condition consultant, another friend seen on these jobs. I joined the PCA consultant for a two beer lunch at the Firehouse Brewery. After that, I skipped over to the library to review city directories, a tedious task made more efficient with a digital camera.

Jesus is Lord of Coalinga - California Dreamin' Part V
Continuing on with my California tour, I left Manteca, the town of Lard, and headed south on Interstate 5, the aorta of California. My destination was Paso Robles. In order to get there I chose to take the long road. The long road went through Coalinga. I'd grown up and lived in California most of my life and somehow avoided Coalinga, or more likely it avoided me.
The road from I-5 to Coalinga passes through a low range of hills peppered with oil well pump jacks, resembling overgrown grasshoppers, similar to their smaller, lowly cousins that rattle up and away in advance of any hiker strolling through these hills willing to chance rattlesnakes and a sockful of foxtails.
Coalinga is actually set in a beautiful valley of pasture, hayfields, and a gravel pit. The town itself is rather bland and on this warm Wednesday afternoon it was unhurried and quiet. I was in need of a big latte and found a local coffee spot just off the main street in what could oxymoronically be called the shopping district. Three teens, a boy and two girls, were sitting around chatting. One of the girls actually worked there and whipped up a 20 ouncer for me. The inside had a smattering of decorative Christian paraphenalia and slogans. I left a nice tip and hit the road.
As a side note, Coalinga was struck by a major earthquake in 1983 that destroyed 800 homes in the town. The quake was felt over a wide area, as far away as Los Angeles and western Nevada.

Pombo Country and the Washington Connection - California Dreamin' Part IV
A leg of my California tour last week took me from San Leandro in the East Bay Area to my next project in the San Joaquin Valley farm town of Manteca, which means lard in Spanish. I had a hotel reservation in Tracy, just west of Manteca.
A steady stream of traffic flows eastward on Interstate 580 during the late afternoon commute. The Bay Area extends its reach east all the way to Tracy and beyond, where workers priced out of the market in the Bay Area find more affordable cookie-cutter squeaky clean tract homes in the flat farmlands of the northern San Joaquin Valley. Tracy, it seems, is evolving into a bedroom community. Large tracts of land around Tracy are for sale and the signs facing the freeway are all Pombo Real Estate.
At the heart of it all is Richard Pombo – “Rancher and Congressman,” which is the slogan one sees everywhere on the campaign signs as the November election approaches. It’s the kind of slogan you would expect would ring solid with the electorate of this agricultural area. Pombo is the powerful Chairman of the House Committee on Resources and is running for his eighth term in Congress. He is known as a strong advocate of private property rights and not exactly a friend of the environment.
I first heard of Richard Pombo in 2004 when the Wild Sky Wilderness Bill was being discussed in the House Resources Subcommittee on Forests and Forest Health. The bill would have designated as wilderness 106,000 acres of lowland forest and high mountains of the western Cascades area around the Skykomish River. The bill had broad bipartisan support and input from many stakeholders, including snowmobile and off-road vehicle enthusiasts. The bill twice passed the Senate, only to get stalled in the House Resources Committee, never being voted on in the full House. In a committee hearing, Chairman Pombo expressed reservations about 16,000 acre portion that the Forest Service did not want included as wilderness.
Back then in 2004, Representative George Nethercutt, a Republican from eastern Washington was contemplating a run for Senator Patty Murray’s seat. Senator Murray was a prime sponsor of Wild Sky in the Senate. Nethercutt needed to show he had the environmental credentials with the voters of western Washington. He took it upon himself to work with Pombo to make changes to the bill that would get it out of committee and onto the floor where passage was assured. The whole thing turned ugly when the compromise proposed by Nethercutt was unacceptable to the bill’s original sponsors, primarily Representative Rick Larsen, Democrat, in whose district the Wild Sky Wilderness would fall. Chairman Pombo withdrew the bill and said he acted after being told that the Washington congressional delegation couldn't resolve their differences.
As it turned out, Nethercutt did run for U.S. Senate in 2004. He was thoroughly trounced by Murray, losing by 12 points, receiving only 43 percent of the vote to Murray's 55 percent.
Richard Pombo is quite a controversial figure in his own right. Besides being a forceful advocate for private property rights, supporter of drilling in ANWR, and a reformer of the Endangered Species Act, he’s also paid significant amounts of money to family members out of campaign funds, supported the construction of a freeway to enhance the value of real estate he owns, and had links to Jack Abramoff. Currently Pombo is running against Democrat Jerry McNerney for his congressional seat. The race is becoming a close one. A recent poll showed McNerney leading by two points.

Rumblings a Reality
Sunnyvale is go. The site historically had a dry cleaner and two gas stations. Sweet. I have a probe rig penciled in a week from this Monday. I'll be in the field Monday morning in Sunnyvale, meeting a colleague from our Roseville office. I'm working late wrapping up reports from last week's California tour.

Rebuilding New Orleans - California Dreamin' Part III
I know precious little about what is going on in New Orleans these days, other than the dire tidbits of news coverage showing the place essentially still devastated. My company is a subcontractor to Fluor doing FEMA work, mostly damage assessment and engineering. I haven't had a chance to really talk to some of our people who went out there. It required a three month commitment so I never signed on for FEMA work.
Flying down to Oakland last week I struck up a conversation with the flight attendant in back, an African American. He liked the fancy metal luggage tag I had on my computer bag and wanted to know where he could get one. He asked me what I did and we talked a little about geology and mold. His girlfriend studied geology at the University of Louisiana. When we hit on mold, he told me he had bought eight houses in New Orleans and was in the process of gutting and rebuilding them. He'd had mold abatement done. But his optimism about New Orleans was what really struck me. "It's coming back" he said, "better than ever." I believed him. It gave me a lot of hope and optimism about the future prospects for New Orleans. I wondered how many others like him were doing the same thing. Perhaps this is how New Orleans will come back, from the grass roots. And the Saints are undefeated so far.

Saturday Work
I had to go into the office today and put together some materials for an upcoming in-house training class called "Fundamentals of Environmental Due Diligence." It's all about Phase I stuff and the new USEPA All Appropriate Inquiry rules and the corresponding revised ASTM E 1527-05 Standard Practice. I hate working Saturdays but I'm swamped and I couldn't put this off any longer.
Through the Salinas Valley - California Dreamin' Part II
I started to leave Paso Robles around 8 am Friday morning, with a quick stop at Starbucks. Did you ever step into a Starbucks that had an attitude about it? Kind of an uppity, not very friendly attitude? This one had it. It's the Starbucks at the south end of town in a brand new shopping center that has all the same stores I've seen in about 10 new shopping centers going up in Gilbert and Chandler, Arizona. I found a nice coffee place in town, Jax Coffee House, but I didn't want to go through downtown Paso again. Jax has great tasting coffee, but $4.10 for a venti nonfat latte is a bit steep.
I headed north into the Salinas Valley - Steinbeck Country. John Steinbeck and Wallace Stegner are two of my favorite authors.
I stopped in San Miguel and toured Mission San Miguel Arcangel, the Rios-Caledonia Adobe, and then photographed a little at an old feed mill on the north end of town. It was all old California and I savored every exposed adobe brick minute of it.
I took a slow drive through King City, following the trace of old 101 as it does a 90 degree turn through the town, just to try and conjure up memories of family camping trips to Oregon when we followed this same route.
Another mission, Mission Nuestra Senora de la Soledad, out in the middle of the lettuce fields. Blissfully silent in its isolation. No one else there to disturb my solitude.
Looking at the clock I realized I could make a 4:55 pm flight out of OAK instead of my later 8:30 pm. I took the slow River Road to Gonzales. There I phoned Southwest and booked the earlier flight. I drove straight and fast up to Oakland and made it in plenty of time to get a "B" group boarding pass. I can usually get an "A" group pass by going on-line the day before. I just hate the whole gamesmanship and lining up thing about Southwest's A-B-C boarding group B.S. I still snagged my favorite seat - 20E. It's way back but comfortably uncrowded if the flight is light. You know, everyone wants to crowd upfront. That's fine by me. Plus, 20E is behind the wing, offering good views and photography out the window.
Home in time for pizza and an X Files DVD with the family. Can't beat that.

California Dreamin' - Part I
It's been a good long while since I've posted on this blog. I have promised myself that I'll work harder on this blog and post more often. Much has happened as DudeDiligence - Denver, San Francisco, Ontario (CA), Portland, a wonderful backpacking trip to the Olympic Coast with my oldest son and a wonderful walk on Dungeness Spit with my youngest son, more hikes, a family vacation to Coeur d'Alene, and on and on. I visited Chaco Canyon during a trip to Albuquerque for a meeting. Chaco Canyon is powerful in its beauty and mystery.
This week finds DudeDiligence in California, currently in Paso Robles on the tail end of a whirlwind tour of California beginning San Leandro at a cookie and muffin factory followed by mold assessments of medical office buildings in Los Gatos, Manteca (means lard in Spanish), and Templeton. Tomorrow I cruise slowly back up to Oakland to fly back home to Seattle.
On the way I have found tons of topics I want to explore further:
The rebuilding of New Orleans: met a Southwest flight attendant (an African American) who bought and is in the process of gutting and rebuilding eight houses in New Orleans. He gave me a lot of hope and inspiration.
Congressman Richard Pombo, Pombo Realty, and the Pombo family: I stayed in and traveled through Tracy, California - it's Pombo country and Richard Pombo is the man - rancher and congressman.
Coalinga, California: "Jesus is Lord of Coalinga" I kid you not.
Parkfield Grade: A scenic and remote drive through the heart of the California coast ranges oak savanna.
Parkfield, California: Earthquake headquarters - population 16.
James Dean: died in a car crash somewhere near Cholame.
Paso Robles: a boy and his wooly bear caterpillars.
Castoro Cellars 2005 Fume Blanc: tasty
I'll see if I can explore a mission or two on my way up to Oakland.
