Brain Freeze

When I went out to pick up our son from school this afternoon, I saw a sight that made me wish I had brought the camera:

A guy on a nice bike, in a snazzy bike helmet and a blaze-orange vest, attempting to bike down the ice on the side of the road.

Weather at the time: 15 degrees F., 17 mph wind, windchill around -2 deg. F.

Cold weather makes your brain freeze.
