The Peninsula Science Fantasy Association (PenSFA) holds meetings on the San Francisco peninsula, in California. The purpose of the meetings is nominally to discuss science fiction; contact PenSFA's commander, Rich McAllister, for more information.
Meetings are nominally biweekly, but are sometimes skipped when there's a big convention going on, or nobody volunteers to host; it's rare for us to go for a month without at least one, though.
