I can tell all the people who have never actually lived in a state that has snow removal equipment. In Minneapolis we could get 18 inches of snow and still have the roads plowed and ready to drive on by early mid day. Here in colorado the snow removal is a little more slax but still I have yet to wake up and go there is no way I can drive today. People will get to the stadium regardless of weather because if the game is in a city that has the propensity for inclement weather then the city is already prepared for it. It would be exponentially worse to have it in a city like new orleans where they got a freak ice storm, I lived in Louisiana for almost a decade as an adult, and a half inch of snow could shut the city down. Game day decisions have always been a part of football and weather is one of those considerations and shouldn't be excluded from the superbowl.
