OK that sucked... when I went to bed it was mid 50's and raining. When I woke up it was 24 with freezing rain, sleet, and snow. I knew it was coming and switched back to the studs. Most of the roads and trails were passable just slow, nothing had been plowed. At one crossing I came to what I thought were some blocks of snow until I tried to go "through" one to find out it was ice. Somehow I managed to stay upright but when the crank hit the pedal smacked me in the shin. Argh! I had a 20+ mph tailwind... and I'm taking the bus home!
