I was talking to a friend who rides cyclocross for the Lapierre-Ritchey team yesterday and, remembering this thread, asked him about the NorCal race schedule. He mentioned Pilarcitos (http://www.pilarcitos.com/BASPS.htm), Velo Bella (www.velobella.com) who are putting on the Surf City Series, and Yahoo! groups - bayareacyclocross as some places to get further info.
