This Meetup is a coalition of most of the Bay Area Freethought groups. We post our various meetings, hoping that people will find groups that suit their outlook. A number of Skeptical meetings are also posted here. We're an "umbrella" for a few locations at once: SF, North, East, and South Bays, and the Peninsula.

Some groups post their meetings as recurring, meaning you will see several meetings listed as upcoming. But most post their meetings a couple of weeks before the event. This can give the appearance that meetings are dominated by the groups with recurring events.
