The SF Bicycle Coalition has released an awesome time lapse video of over 1,000 people on bikes rolling by the Market Street bicycle counter on the morning of Bike to Work Day.
The SFBC's volunteer photographer Volker Neumann took photos every five seconds with a camera mounted to a nearby telephone pole.
Photos and statistics are great, but nothing shows the potential to grow bicycling in San Francisco quite like the sight of serious bike traffic in action.
