We've said it before, but we'll say it again: Free beats Cheap anytime! It goes without saying, really, but it bears repeating. And what's a better way to get something for free than by just giving it up? We're referring, of course, to the San Francisco Bicycle Coalition's Gas-Free Fridays. 
It's not that you need a special excuse to leave the car behind when you're commuting, or otherwise travelling around the Bay, but SFBC's Gas-Free Fridays campaign is a way to get out the word on cheap, cleaner, and greener ways to get from Point J to Point Q.
May we recommend some? Of course, there's MUNI, BART, AC Transit, and even SamTrans. Sure, they use power and fuel, but a lot less than thousands of cars do. But the best way to move around is still the good old bicycle. It's cheap, easy, and with all of SF's hills, great excercise!
What are some of your tips on getting around San Francisco for cheap or free? Mopeds? Skateboards?
