Nice commute this AM, just enough light (with the headlight) to avoid iced-up puddles. Very pretty with the sun just coming up and I enjoyed the crunching of frost under the wheels. Had to hop onto the pedestrian path to avoid a wrecked car on the cyclepath - it had skidded on black ice and hit a lamppost. Fortunately no-one was injured. The driver was waiting for the tow-truck and didn't need assistance.
