It's great fun riding in freezing rain. In particular, it's fun freaking out the smokers I pass when entering the building.
One day last year, I rolled up to work over a fairly significant layer of ice, and when I straightened up to get off the bike, a lot of ice broke off me and hit the ground. The bike had about 1/4" of ice on the leading edges.
The year before that, many of the same smokers watched me leave for home in the middle of a hailstorm with pea-sized hail.

yeah, they think I'm crazy. They could be right.
