Chicago Cold

I've been in Chicago for two days now. The temperature has been falling as well as the snow. Jennifer and I saw the move The Kite Runner, which I read (fantastic story). The temperature on the way home was 14 degrees! I believe that is a personal all time low temp for me. The high on Saturday is 9 degrees. I told Jennifer 'who needs a refridgerator when you could keep the food outside'. She said the food would freeze. Which means - the refridgerator is a device that keeps food warm.
