After the success of their screening of Rad and May's bike-in Disposable Film Festival, SFBC is sponsoring another bike-in movie tomorrow night in the parking lot of the Good Hotel at 7th and Mission (8pm). This month's film is Klunkerz, which tells the story of the birth of mountain biking in Marin and how it spread around the world. Mountain bike legend Gary Fisher will be there for a quick Q&A session after the film. And what's a film screening without concessions? Some of SF's favorite street food like Gobba Gobba Hey and the Magic Curry Cart be nearby for a quick bite during the movie. SFBC will provide valet bike parking.
