In your first post when you mentioned that it was cold in August, that made me laugh. The warmer months for the bay area is September and October, although you might get lucky in June.
Railrider, those are some amazing shots! San Francisco is my home town, and it's where I spent a good portion of my childhood. Your shots give me some serious homesickness. Did you get a chance to drive down Highway 1 along the coast from Monterey to San Francisco? Santa Cruz is along that route and I am wondering if you had a chance to stop, as it is absolutly beautiful during the summer.
