Temperature at departure = 9° F (-13° C)
Back in December I mused about what temperature would be my breaking point for not riding the extra loop on the way to work. Turns out that temperature is 9° F. Yesterday, at 10°, I was fine and rarin' to go the extra miles. Today, same kind of clothes, skies and wind ... didn't want to do it.
My bike even complained a little. After sitting in the office for a few minutes it started making several pinging sounds. It happens whenever I ride in temperatures this cold ... I think it's the spokes thawing out. Freaky.
