"Relive the historic occasion of the only U.S. President to visit NOPA and then take a spin and give a nod to six other Chief Executives along our route into Golden Gate Park, through the Presidio, and over the Golden Gate Bridge. Two-hour ride with mild to moderate climbs; all levels welcome. Presidential attire encouraged.

Kids on own bike OK if with guardian. Drinks and lunch follow at Herbivore Restaurant, 531 Divisadero, between Hayes and Fell."
