Tracks in SF Area?
I am contemplating a move to San Francisco, and I was wondering about what tracks are close enough to SF to drive for a weekend (and that are good enough). We are rather spoiled here with premier tracks like Watkins Glen, Mosport, Circuilt Le mont Tremblant, Mid Ohio and Calabogie - all within a reasonable drive. So how are things for those who live in Bay Area? I know Laguna Seca is supposedly awesome, but what about others? How is tracking scene in general?
