I guess when you actually have significantly more fans rooting for your team, it's louder.
If Cowboys Stadium wasn't a 60/40 split every week, I bet it would get noisy.
I think that if Dallas can ever get consistantly good again, we'll have a home field advantage list.
Right now, we suck a lot, so season ticket holders sell their tickets. And the problem with our stadium is, it's SUCH an attraction that rival fans make it a point to travel to it. It's like a bucket list item. Have to see a game at Cowboys Stadium.
