There was a guy in my office building a few years ago who used to use some sort of Shrek thing stretched over his helmet. I first saw it while I was driving home, and I saw these two weird ear-like things sticking out and I didn't get what it was. Weeks later I was leaving work one evening, and saw the fellow in the lobby and asked him about it and found out what the thing was. I have auxiliary headlights attached to my helmet, so this sort of thing wont work for me (have skullcap waiting and ready).

There is a little learning curve to riding in colder weather. A few years back I got hypothermia (it probably wasn't all *that* cold, but it took me the whole day to warm up - even after a long hot shower), so now I am really paranoid about being too cold. That was back when I was riding 19 miles each way, and now I am at about 10-1/2 miles each way, so I am not as concerned as I was before.
