Description (pardon the shaky cam-work - the bridge is jiggley and I'm using a camera that's about 800 years old.) Was biking on the Williamsburg Bridge this afternoon, and was getting ready to scream at the group of people stopped on the bike path... when I noticed that the reason they were all stopped and gawping upwards was that there was a neat chick (edit: Seanna Sharpe) doing some sheet acrobatics, hanging from the middle span of the bridge, which is super high-up. Good for her. It was fun.
