Here's the build:
-Shimano Ultegra 28h front, silver d/b spokes, silver alloy nipples, silver Velocity Aerohead rim
-Surly fixed/free 32h rear, and same spokes, nipples, and rim.
This is now the third set of wheels that I have built, and wheelbuilding seems to only get more exciting. The lacing felt a lot more natural, and I didn't have to think about it as much as the first two pairs. I did, however, verify with Chaz that I was starting correctly. The Surly rear hub was very easy to tension because of the symmetrical qualities of the hub flanges.

I've still been riding a lot lately, and I'm feeling great. I do have a slight knee problem that kicks up every once in a while, but I think I've figured out how to take it easy on my knees. Yesterday, I went for a single speed ride with Chase and Justin. They both ride brakeless fixed gears, which I think is a bit crazy. It was very windy, and we took turns pushing for short periods of time. It was about a 30 mile loop up to Annadel and back.
Today, on my one day off from everything, I decided to go for a nice and long ride. As indicated earlier, I am loving the single speed, so I took it out. I just rode out and around the neighboring cities on the country roads and made up the route as I went along. There was a mad headwind the first 30 miles, and I was in the drops most of the time. I was standing and mashing into the wind on the flats sometimes because of the wind. When I finally turned around to go back down to Rohnert Park, I really appreciated the tailwind and flew back at the top speed I can push with my 42x16 gearing, which is somewhere around 23 mph or so. The ride ended up being 50 miles long, and I feel great now, afterward. I think I want to push for 75 miles next ride, as I am still contemplating whether or not to try for the 100 mile ride in the Tour de Cure, which is one month from today.

So what's next for my single speed?
Aaron Abravaya and I will each be picking up a White Industries freewheel for our single speeds (Aaron's is a 29er mountain bike). I hear the quality is impeccable and I will be very happy when my freewheel doesn't make a constant clicking sound while pedaling. I also like that they are a VERY local company, fabricating their products in Petaluma, CA. I am very impressed with their road hubs, additionally.
It was a beautiful day (but still windy):

Rear wheel awesomeness:
