My commute Friday was not as bad as I though it would be. I drove my daughter to work at about 8:00 am in blizzard like conditions and the roads were very slick. By the time I left home on my bike the snow had stopped, it was 30 degrees, the roads were just kind of slushy and the 20mph wind was mostly at my back. After work is was 23 degrees my derailleur were frozen in a low gear. With my normal cadence could only achieve about 8 mph but that was good as I had a 14 mph head wind. I kept warm though.
