I believe that you are correct. A lot of the people that leave early seem to be long time season ticket holders, that have been to more than their share of Packer games. They would rather beat traffic, then watch those final minutes. If you have ever gotten stuck in Green Bay traffic for an agonizing hour after a game, you probably can relate. There are not many sidewalks in GB, so fans seem to like to just walk slowly in the middle of the roads, which also slows up traffic. Not to mention that dependent on which way out of GB you are headed, even when you get out of GB, traffic is super slow for the first hour. So yeah, I get why some leave early, and I have as well. That said, if its a close game, I'm staying until it is decided.
