Coldest commute in a while with temps in lower 20s F. I know it's cold when my water bottle freezes. Catching nearly every red light on my route didn't help matters, particularly the one with the sensor that wouldn't detect my bike. I sat through 3 light cycles waiting for the red to change to green, and it didn't trip until a car pulled up behind me. Grrrrr.... I can't run that light because it's a busy intersection, plus my eyeglasses fogged up waiting so long for the light to change.
