Bring your bikes to Justin Herman Plaza between Market Street and Embarcadero and meet on the northeast side of Vaillancourt Fountain at 11 am. All types of bikes are welcome – tandems, unicycles, music bikes, you name it. Skaters and skateboarders have also joined past rides.
Bring body paints, watercolors, and markers to apply slogans and designs to each other and adorn your bikes with signs. Use black to mimic an oil spill or green to celebrate the environment. Tentatively, you will be going to the outer edges of Golden Gate Park to Ocean Beach and the Great Highway, south to the San Francisco Zoo and back to the heart of the city, finishing up around 5 pm.
