Low 30's, slight headwind. Forecast is threateninga major winter storm, but when I left, the streets were barely wet. Nice good pace, bike was working good too. Still a bit overdressed, coulda lost the balaclava. Anyhow, as I start to climb the hill over I-270, the snow/ice begins. Tiny little ice pellets, traveling at high enough velocity to sting when they hit skin. Slowly they get bigger. As I start my way down the other side of the highway, my front tire flats - from what, I have no idea. Kept control, and hoofed the rest of the way to work (only a stones throw, took maybe 3 mintues).

Second flat of the year. grrr. At least I'll have something to do on my lunchbreak. Still, a good ride though. The way home will be interesting.
