All in the space of 12 hours. It really does interesting things to driveways and roads. School was cancelled because it was too warm. Too much ice makes parking lots and roads skating rinks. I would not mind if the temperature went o 20 and stayed there until breakup. Doing the penguin shuffle until breakup is the pits.
Penguin shuffle is where you do not lift your feet off the ice. All you do is shuffle along.
