I have a friend who races at Hellyer in San Jose. He's frustrated that the majority of the races there are not USAC, and the USAC won't recognize his results to progress through the categories. What's the scene like down there?
I haven't been in a while but I recall there being plenty of official USAC racing at LA and San Diego. During the week and such are just A/B/C categories I believe. I'm a cat 3 but primarily doing time trialing so I can still do most of the mass start short of international stuff.
