With the success of Zip Car and big changes to SF streets in the pipeline, now is a better time than ever to trade in your car for something without monthly payments and parking challenges: a bicycle! Every year, New Belgium brings their traveling music, beer, and bike festival, Tour de Fat, to Speedway Meadow in Golden Gate Park (this year's party is Saturday, September 26). For every city on the summer tour, New Belgium selects one aspiring carless citizen to exchange the keys to their car for a new bicycle in an on-stage ceremony at the event. And if you're the San Franciscan chosen, the lucky carless citizen will be you!

Entering is simple: If you're on Facebook, visit the Tour de Fat San Francisco event page, submit video (2 min or less), photo, or text to the event wall explaining why you should be the one picked to trade in your car for a shiny new bike. Not on Facebook? Email zlevis [at] newbelgium.com. Winners will be announced 2 weeks before the event, so you have just a little over a week left to enter.
