I started riding in that city, only raced a training crit once though, so no useful information on racing per se.
However there is a good group ride on Sundays. Used to be at 7am I think? Not official by any means, but a good 70 mi or so. Look up the "Knucklehead" ride or call ahead and ask the folks at Big Shark or Mesa Cycles. They might be able to clue you into the start time and where it is still happening.
Its been a few years so I can't say anything for sure...
