Don't know who, but some crazy guy with thin, slick tires did a nice 180 on the MUP bridge before I got there. Didn't see it, but saw the track. I'm assuming it was successful since I didn't see an awkward snow angel near the track.

I rolled into work at about 8:30, and mine was the 5th track in the snow. Thought I would have been the only moron!
