You know what to do.  Put your butt on a bike and ride, ride to work!

San Franciscans, show your local San Francisco Bike Coalition support and stop by one of their 27 Energizer Stations.  The nice folks at REI will  be located at the station by Kearny and Washington in Chinatown from 5pm-7pm with a certified bike technician to make simple nut and bolt adjustments to your bike-for free!
