it takes away that outer layer of heat that surrounds your body. hypothermia can set in with a body temperature drop of only 2 to 4 degrees. when we are talking about these temperatures, you have to keep in mind the folks that are going to brave it say around noon outside, the temperature will be minus 1, but the windchill will be aut minus 18. even for on the actual start of the game, say around 6:00, 6:30, for the folks huddling into the actual stadium, the temperature will only be about 3 degrees. here is the thing, a lot of folks keep saying it is the c coldest game on record. some think it is unfair to count a dome game as the coldest, but the coldest out door game was in new orleans back in 1972 with 39 degrees. you re talking about a high of 3 at the game. so no comparison for the folks just walking into the game. it will be incredibly cold. are you ready to go cover it?
