Go City Kids, a great resource for kid-friendly events.
A friend pointed me at Go City Kids, a meetup-esque calendar of kid-friendly and kid-focused events. They have several metro areas, one of which is San Francisco, and most of the events listed there are in the city proper, although there are a few in San Jose and the bay area. Some look like they may even be worth a trip up to the city, so check it out!
