"Get on your bike and celebrate Gas-Free Fridays! In San Francisco, half of all driving trips are under two miles in length -- a distance easily traveled by bicycle. So, grab your bike and a friend or co-worker and pedal by one of the SF Bicycle Coalition's Service Stations to fuel up on free coffee and snacks.
Share your bike love at a Gas-Free Friday Service Station, sign up to Volunteer for Gas Free Fridays."
