There are several good clubs in the Bay Area, but in San Francisco proper, the only homebrew club several of us have been able to find, San Andreas Malts, appears to have stopped meeting (at least publicly-announced meetings) and has not responded to email inquiries. (There is one recent post on the club's website about a proposed "toast" to a deceased member, but it doesn't have info directed at people unfamiliar with existing members.) Does anyone have different information?
