The NFL is busy making rules. First was a code of conduct for the players ... then a code of conduct for fans in the stadium.

Now Roger Goodell wants to tell you how to act when you are tailgating, too:Fans will no longer be allowed to tailgate in certain parking lots during NFL games, unless they have a ticket. Security guards will now sweep through parking lots at kickoff, booting everyone without a ticket. The NFL says the new rule is to prevent fans from getting too drunk and causing trouble.
