SFBC Pavement to Parks Ride

"Join the San Francisco Great Streets Project as we check out the sites
of San Francisco's newest public space movement. Starting at the City's
first Pavement to Parks Site in the Castro, we'll continue on to the
three sites soon to be reclaimed in Potrero, Southern Mission and the
Excelsior. All are welcome, will not be a strenuous ride. Heavy rain
cancels."
