I live in northern illinois now. This is my first winter up north. Everybody here is telling me that winter gets too cold to commute by bike on, even though the town I'm living in is no bigger than 2.5 miles across. I'm sure somebody out there cycle commutes in the winter (i've seen the pictures of bikes here outfitted for winter commuting) so it can't be impossible. I intend to at least try it. Anybody have any advice, recommendations, proverbs, etc.?
