I can speak only for my own little corner of San Francisco, but like others here I can say there is DEFINITELY an Analog Photo aspect to the Bay Area. It is not, as of yet, organized. I would like to put an offer out here though. If anyone would like to have some type of APUG meeting in San Francisco, I will gladly volunteer a meeting place: Newlab. We just moved to 8th Street and have a pretty cool space. So...if anyone feels up to it, please feel free to contact me about using Newlab as a place to meet. The one thing I hear over an over again is the lack of community that photography offers these days (most people miss that part of going to a lab to drop off film) and I have always seen good come out of people meeting and sharing ideas about photography.
