I learned to race track on the Olympic velodrome of old. My coach had a key and we used to motorpace until very late at night. Winters, such as they are in LA, could be cold and damp; we often had to stop use of the track when the moisture came up through the concrete in turns 3 and 4. That said, it's is really hard to beat the Velo Sports Center (the new, indoor, wooden) track. I missed the LAVRA race this weekend, but will probably do many of the other TT's. I am thinking of doing Omniums also, but they are only offering a 40+ class; at 65 it's a little hard to keep up!
