For years there was no tailgating at Texas stadium.
When Jerry bought the cowboys he changed that, but can't remember what year. And then the city of Irving limited it to certain parking lots. People just couldn't set up and tail gate wherever they wanted.
Maybe it's like that at other stadiums, but does not seem like it. So you don't get the tanked up loud fans right away being loud.
Not saying this is the main reason, but it contributes to the problem.
At the new stadium, it's also limited, you can only set up to tailgate on the perimeters on the lots.
At least for cooking food. Again I believe this is the city of Arlington controlling this.
So you can't get the party crowd loud atmosphere at the beginning of the games, and unless you want to spend $9 a beer and drink them fast to get in that rowdy crowd mood. it's just not going to happen, if you want that atmosphere. Which seems we never have that loud endzone crowd either.
They just sit there on their phones and ipads.
