I looked at the snow and went "oh fer cryin out loud" - then put on my fleece tights and rode anyway

Actually it was great, roads were wet but nothing worse, and I was just the right temperature in my layered clothes (some of which still smell like campfire smoke from the weekend, heh). My only complaint was cold wet feet. I may do the baggies-over-socks thing on the way home.
Had to do one detour because of downed branches on the MUP, so I rode in traffic. Drivers were very courteous about giving me room (I think they probably thought I was dangerously insane; my co-workers agree).
Saw about 15 other commuters - about a tenth of the usual!
