Today was my first real winter commute (after a failed attempt yesterday during a small snow storm).

Coming back from work at 11PM, the weather was -20C/-4F with gusty winds. With 6 KM to go, I decided to adjust my seatpost's height... My seatpost quick-release pin quickly broke when I tried to release it. The rest of the ride was spent sitting 6" too low on my old hybrid, with the saddle going to and fro with its red blinky, knees up there like those cool dudes on downhill machines. Still, a nice ride, albeit a bit rough on my old knees.
