SUPER BOWL POST 2

Why does the Super Bowl always have to be played in warm weather or indoors?  Everyone talks about how great playoff football is in the snow, wouldn't the Super Bowl be that much more fun to watch?  I realize that people putting down thousands of dollars to go to the game probably don't want to sit in the snow four and a half hours, but phooey on them.  Play the Super Bowl in Buffalo or Green Bay.  That would make it real winter football.
