G2SF ride, 2 seconds & train track traps

Today, Russ, Joe, Nick and myself went on a ride from Google to SF. We left under an overcast sky and a chill to the air, but the forecast said it was going to be a gorgeous day. We left the shop thirty minutes after our intended "wheels rolling" time. It was chilly at first but quickly warmed up after a mile or two, but my hands were chilled because I forgot to bring my full-fingered gloves.
Joe was asking where the taco trucks were since he apparently skipped brekkie and was hungry. By the time we got to Belmont, we stopped at the Burger King next to the small airport. Twenty minutes elasped before we got back onto the bikes headed toward our goal. We left the parking lot down the road, and had to make a left. Nick rolled through the stop sign just a a pickup truck came towards the intersection. I was going at a good clip, hit the brakes hard coming to a stop next to Joe. I was still clipped in and intended to clip my left foot out, but my ankle still not having the strength to clip outwards (as is my norm) I attempted to clip out by twisting my ankle inwards (which up til now worked great). I probably trackstanded for a good two seconds before keeling over to the left like a tree felled by a lumberjack. My shoulder took the brundt of the short fall so no harm done to me nor the borrowed bike. Not long afterwards, we hit the spot on our route that was a good long run which paralleled 101. Using the slight downhill, I ramped up my speed to just haul til the end of the bike trail which emptied out next to Postini, a recent acquisition of Google.
We continued on through Redwood Shores and at one intersection, Joe rolls up behind Russ and me and says, "Nick, I'm two seconds away from punching you in the back of the head". Joe was pissed that we (Nick and I at the time) we going along at a speed Joe couldn't keep. Joe didn't have clipless pedals and cycling shoes the rest of us had. He went on to complain that we were on a "group ride" and not a race. We left the intersection and reduced our speed to appease Joe. A couple miles later, Joe appoligized.
We quickly passed through Coyote Point and SFO. We again stopped at the McDonalds in SOuth City for a piss break. Joe complained about his wrist and shoulder which he injured during the holidays. As we passed Brisbane, approaching SF proper, we saw the first and only steep hill on our route. I made quick work of it with a minimum of effort. I dont know whether it's because of the gearing on the borrowed bike or better fitness since the last time I rode this route two months ago.
The rest of our ride towards downtown SF would be primarily downhill except for two moderate hills. We made it into the heart of downtown around 12:30pm and made straight for the SF Google office on Spear street. We stored our bikes at Google and headed to Palomino for a well deserved lunch. After lunch, we quickly headed to the Caltrain station on 3rd and King to catch the 3pm train back down to Mt View.
It was a great day for a ride. The company was great and entertaining as well as an exercise in group dynamics. I felt better this time than the same ride I did with Russ two months earlier.
