From this month's Meetup Organizers, Dennis and Doug (Lonan):

Hi Dads! Our next meetup will be Saturday March 21 at The Bay Area Discovery Museum at Fort Baker, just across the Golden Gate Bridge near Sausalito. We'll meet between 2-2:30PM in the outdoor playground at the back of the complex. In the event of rain we'll meet in the lobby and move on to one of the multiple indoor play areas. After the kids are (hopefully) worn out, we can migrate to the Cavallo Lodge next door for a drink. There's a nice patio and a huge lawn where the kids can continue to run around safely. http://www.baykidsmus...
From the web site:
The Bay Area Discovery Museum is a one-of-a-kind indoor and outdoor facility at the foot of the Golden Gate Bridge, serving over 300,000 visitors per year on its 7.5 acre Sausalito campus. We are the only children’s museum in the U.S. to be located in a national park, and our exhibits are admired and emulated by other children’s museums nationwide. The Museum is recognized as the leading children’s museum dedicated to developing childhood creativity, nurturing future generations of creative thinkers and innovators. With this emphasis on creativity through play, we encourage children ages 6 months to 8 years to develop into curious, creative, adventurous lifelong learners and explorers.

The Museum's unique programs feature hands-on art, science and environmental exhibitions, performances, special events, cultural festivals and ongoing educational curricula... all with a focus on fun!
