Dang dang dang! I don't have studded tires for the new bike yet, and this morning the commute was coated in a fine sheet of frozen sleet. No way the Conti UltraGatorskins were going to work on that slickness!
Ended up driving in

due to that, and the fact that my fiancee asked me to drop her off at work because she wasn't going to try driving her car in this stuff. (She's got a light, sporty little car w/ too much torque for its own good. Fun in the summer, sux on the ice.)
Gotta buy a pair of studdies once we move, because the new place is 600' higher than where we are now and gets much more snow/ice. Current place got about 0.25" of freezing sleet. New place got 2.5" of snow on top of some freezing sleet.
