I rode to work yesterday at 7F, which breaks my previous record of 16F. I rode home at 9F. I rode in today (on my own bike, vs. bike share for the first time this year) at 10F, so things are improving. Mind you, the commute is only about 15 mins., so not much of a challenge compared to some here. I managed to overdress a little, at least on my top half; I don't have adequate gear for my lower half, but coped for the short ride. The bigger challenge will probably come tonight, when I have to go 10 miles uptown, and then 13 miles home. It'll be a balmy 23F, but with much longer exposure. I've done the trip with temps in the 30s, but not yet in the low 20s. Truth be told, I can always bail out and take the train, but that would be a shande.
