There are 3 tracks in SoCal;
Encino: http://www.encinovelodrome.org/
ADT Home Depot Center: http://www.lavelodrome.org/ and http://www.homedepotcenter.com/event...ompageid=10923
San Diego: http://www.sdvelodrome.com/

All have beginner track racing programs. The closest track to your house (ADT) also happens to be one of the best in the country. I love riding there. Roger puts on a great program. There have been several people that have moved to SoCal just so they can train and race year round on his track. It's a little more expensive because you're also paying for an indoor facility, but it really is fun to ride and there's nothing like dropping down 2 stories of wood banks to the pull line. Nowhere else in the state can you get a 250m wood track with 45 degree banks. Eninco is 250 meters, concrete, outdoors, and about 26 degrees bank. Still very fun just different. It's also good to ride more then one track for experience as well.
