I bike commuted every day this week -- my first 5 bagger in a while. Not only that, but it was the coldest weather we've had since early last spring and I had to work until 9 pm one night. I love this kind of weather -- sunny with chilly mornings and warm afternoons. I probably commuted more days and miles this month than ever, and got my monthly mileage over 600 even though the weekend rides have tailed off.
