The Bay Area Footbag League hosts a Fall Festival every year that features a Pro-Am doubles net event. This is your opportunity to pair up, at random, with some of the best competitors in footbag for some doubles net fun. Even if you have never played net before, this is a great day to learn how. There is also a freestyle shred contest, and plenty of circle kicking and pickup games.

Peacock Meadow is in the very east end of Golden Gate Park in San Francisco
near the intersection of Fell and Stanyan.  Park along Fell as you approach
the park, then walk into the park on J.F.K. drive, which is closed to cars
on Sunday.  Peacock meadow is on your right, just before the large white
Conservatory of Flowers building.
