San Francisco is home to some of the sexiest sporty girls around. I’ve seen girls ollie over MUNI tracks in mini dresses, met women at cocktail parties who still have climbing chalk under their fingernails, and witnessed a parade of skirt-wearing ladies bike down Market Street.

This for week's Scenes of the City we hung out inside and outside of AT&T Park for a couple odd events. One was the aforementioned Cal Bears football team playing in the park (they will be playing most of their home games there because of renovations to their home field). The other is the first-ever water polo match in McCovey Cove. As part of effort to garner support for their sport, the UC Berkeley Alumni Water Polo team vs. The Olympic Club Water Polo team played a match in the somewhat frigid waters of the bay.

Welcome to Chain Gang, our new weekly bike blog– your guide to Bay Area bike culture and happenings, and news.

Think back to when you learned to ride a bike, maybe the first time you successfully raced down the street on your BMX (mine was fluorescent pink) or a big banana seat Schwinn.

For most of us, that involved months of clunky training wheels, which were really nothing more than glorified shopping cart wheels that rattled along behind us. Not so anymore. Training wheels have gone the way of…well, banana seat bikes.
