So a couple days after posting this it got cold in Chicago. It was around 0 to single digits M, Tu, and W. What happened? My hub pawls froze half way through my 9 mile commute. Had to lock it up and take the L, not too bad. I think my "line" would be warmer if it wasn't so easy to quit.

Edit: This happened on Tu morning. Hub was fine on M. Walked it home that night and swapped wheels and was back on the road W.
