I'm not in the bay area myself anymore, but I do know of at least a half-dozen active APUG'ers who live out there, and I drag my LF kit with me anytime I get out there myself. There are still a number of decent camera stores in SF and environs - Gasser's is still around (I think), there's a Calumet in SF on Bryant street, and down in Palo Alto there is Keeble & Shuchat, which is a VERY cool place to shop.
