18F this morning, left early so about 1/3 of the ride was in the dark. It was my first commute on my new (to me) winter bike that I finished this weekend. I bought the frame at the local bike co-op, the rest of the parts were from my wife's old bike and my boxes o' parts. The only things purchased new were fenders and a chain. I'm really happy with it - next steps are studded tires and eventually drop bars.
