I was at this game

I had on at least 3 layers of clothes plus my gigantic mission parka and even though I had just flown out specifically for this game I was seriously considering leaving at halftime because it was so miserable and cold. It was awful. Wind, humidity, cold. It was worse than -50 in Fairbanks for whatever reason.
