Does anyone remember the LEGAL off-road riding area on Redwood Rd in Oakland? Access was by the pullout where all the cafe racers hung out. IIRC there were even sanctioned trials events there. Also Pt Richmond, and I used to play at a nice little moto-x circuit down at the Berkeley Marina in the early 80's. All gone now ... Redwood Retreat plus the few bits of Highland/Summit are all I know that are still legal, unless you get out to clear creek etc.
