Frozen. It was 16F when I left this morning. The MUP was a crunchy mess of re-frozen footprints and tire tracks (and a snowmobile track at some places, and one set of x-c ski tracks.) My hands and arms felt like they were going to rattle out of the sockets.
I put a Conti Vapor 2.1" up front and some cheapo $12 Kenda mudder 1.95" that I studded with cut down roofing tacks in the back. No slip grippiness (is that a word?) and I wasn't really all too slow, considering the conditions. Usual morning ride takes me about 35 minutes; today it took me about 45, almost 50 minutes. For 6 miles on crunchy, chunky, icy MUP followed by 1.5 miles on a still icy slick city street (with a 3/4 mile uphill,) I think I did OK.

I also stopped 3/4 of the way up the hill to take a picture of an Acura NSX that was off in the ditch. The license plate: "PWN" I couldn't have photoshopped something funnier than that. I really hope it turns out since all I had was my camera phone with no flash, so I used my headlight to light the shot.
