Hi Mark, another valuable resource (and a good sign of life for traditional photography), is the Rayko Photography Center in San Francisco:

This is an incredible place with a ground-breaking gallery (I can say that because I'm showing there next month), excellent classes, a rental studio, and some of the last color and B&W rental darkrooms in the bay area. There is also an excellent digital department.

The folks at Rayko are all enthusiastic advocates of traditional photography. In fact Michael Shindler has started a collodion program there that has really taken off. So if you are in San Francisco and looking for a community of enthusiastic and like-minded creative people, I recommend that you do some work at Rayko's facilities or take one of their classes. It has been a great experience for me.
