Some pretty fun antics go down in San Francisco at late hours. I was trying to find Pandora Karaoke Bar last Friday when I came across this flashmob of rollerbladers, skaters, skate boarders and people on various wheeled devices. An announcer was challenging more and more of them to make it down the escalators on their wheels, and one guy not only accepted but jumped over 4 people laying side-to-side and made it down the escalator backwards.
Does anybody know what group this is that rides around SF late at night? Props to them. (risk management lag!)
