I just saw the coolest thing.

Frederiksen Court (where I live) is connected to campus through a, probably 30 foot long, tunnel under some train tracks. People often bike and skate through the tunnel at relatively high speeds. I was coming in from the campus side and a guy ahead of me was biking out of the under end of the tunnel, when I heard "OH SHIT!! OH SHIT!!" and a guy going REALLY fast came down the hill and SLAMMED into the brick wall next to the tunnel. Then he flipped around a little and landed on his back inside of the tunnel. Everybody was like "Oh my god!" But he stood up, started laughing, and said he wasn't scratched at all.
