From SFBC:

What will it take to make San Francisco a world-class bicycling city, where continuous prioritized crosstown bikeways offer safe, comfortable, inviting routes for people of all ages and abilities to ride? With Connecting the City, the SF Bicycle Coalition sets out a road map to the realization of a healthy, happy, sustainable San Francisco that’s great for bicycling. What will it look like, what will it take, and where do we start? Come along on one or all of these rides (see 10/23 & 11/13) examining three Priority Bikeways set out by Connecting the City to get us from here to there, by bike.
