From SFBC:

San Francisco’s southeastern corner has great neighborhoods and waterfront open spaces — how can we do a better job of connecting them by bike? Come out and explore ideas for bikeways from the Mission to Islais Creek and southward, ride the Bayview Wiggle, and check out other opportunities to connect the southeast by bike. Expect a two hour ride, maybe longer, more leisurely than athletic but you’ll get a workout for your imagination as you help visualize the future of bikeways in the southeast.

SF Bicycle Coalition recreational rides are free for SFBC members (a $5 donation from non-members is appreciated); rain cancels rides.
