SFBC Gas-Free Friday
"Declare your independence from oil when you pedal your way to an SFBC Energizer Station on Gas-Free Fridays to fuel up on coffee, tea and snacks. The SFBC wants to help more people substitute one short car trip with a bicycle trip just one day a week. 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 encourage a friend or coworker to go gas free."
