I will be in town during those dates, sounds like a plan to hit them. I also know that Fort Mason has a small gallery, there are several near on or near Market street and union square area, I can walk right to them just don't know their names. Some times the Place of fine arts has a photography display. Going out further than the City or Oakland, I highly reccomend hitting the Mumm Winery in Napa. They have a wonderful gallery, and a permenant rotating gallery of at least 40 of Ansel Adams orginal prints.
