Not Bolinas - a nice sandy beach north of that one great big, geologically important point created by the San Andreas fault (granitic material on one side, coastal sediments on the other). thigh to chest high, glassy through the afternoon, got a few 30 to 50 yard lefts and rights with enough push to get a small, wide board going. bunch of old timers out on logs. Also spotted a nice dolphin couple cruising around a couple hundred yards offshore. fair enough for me.
