Thanks guys. It doesn't get terribly cold- I've never needed a helmet cover because I get warm in five minutes, so I bought some cheap rubber pants and they work really well and are light. I thought about getting some booties, but I don't have bike shoes at this point, so I'm thinking I'll just get a pair of shoes for biking and some wool socks and just wear those when I ride. It is good to hear that other people roll the bikes throughout the winter.
