We have an RV pass to the Arkie game and expected to tailgate, but have 'heard' repeatedly and been told by Cowboys ticket staff too there is no tailgating whatsoever, even on the grass. This is so folks have to buy the overpriced beers and margaritas from various Cowboys vendors throughout the parking lots.
This may be an RV thing, but anyway, if you can post a link or confirm again that you have seen it, I will look again and would love to be wrong.....how they enforce it is a questionable...
