As a new winter commuter, I've been gearing up and mentally preparing for the snow, ice, darkness which would either freeze me, make me fall or see me rammed by a car. Today, danger from an unexpected quarter - my office building's garage door closed onto my head as I was riding in. Lucky for me was going slower than usual due to ice near the entrance but was still rolling about 10 miles/h when my forehead slammed into the closing door cranking my neck way back. Took a small chunk out of my helmet and left me dazed, neck is still pretty stiff.

I used to be happy when I would arrive at work to find the door still open from the previous car since it saved me having to do the little dance that triggers the auto-open. No longer. Beware all, those doors are evil.
