[Rain Man]

Here in Colorado we have snow machines for the ski slopes. Perhaps as a compromise the game could be played in a warm weather city for fan comfort, but the field conditions would simulate the weather in a rotating list of franchise cities. So for example, in 2015 the Super Bowl would be played in New Orleans, but the conditions on the field would simulate the weather in Buffalo on that particular day. You could add rain, snow, sleet, whatever.
