I'm a newbie winter commuter too Here it usually gets cold when it's dry (so far the lowest has been 31 - 32 F) but mostly it rains so it's not so bad.

I'm anticipating that my biggest problem would be ice on the road because I work up a hill where temperatures are a few degrees lower than where I live and there are some sharp turns on the way too. It's also steep, so it might get dangerous on the way home. I don't think I've ever ridden on ice before, so I guess I'll just wait and see... Maybe I should find a way to practice what to do in case of skidding and falling down...
