Just a heads up for everyone that Track World Cup is back in LA January 19-21, 2007. It's a chance to see the best riders in the world going at it in all track disciplines (from sprints through madison) in a nice venue where you can see all the action all the time.
Unlike the Tour o' California where they go past in about 45 seconds at the slowest part of the race (top of Balcom Canyon) you can see all the racing all the time on the track, plus the warmup and cooldown, and somtimes the riders who are done for the day or the weekend will come up and sit in the stands to watch. They're often pretty friendly and will chat or answer questions, too. I sat behind some women from the british team while their teammates won the madison one year, and chatted with some of the kiwi team another time.
Details about World Cup (and riding on the LA track in general) are here http://lavelodrome.org/Events/WorldCup.htm
(mods: this really is a socal thing, not a track thing-- there are tons of people from the Socal forum who live within about 30 minutes of the track and don't visit the track forum but might like to watch, and there are about 5 people in the track forum total, most of whom live in other countries and couldn't get here by the 19th).
