First off, the Stadium is beautiful. Plenty of accessible vendors, great variety of food and drink, and easy to get around, near by parking. The stadium itself was the highlight of the event.
The bad news is that I have never seen a group of fans as ignorant, rude, and outright mean. From people standing and never sitting and yalling at people behind them after being asked nicely to sit, to the people that would yell "stab him in the ass with a dagger." We were sitting in the family section and the amount of curse words spewed every second made everyone in my group very glad we didn't take any children with us. People around us were also unknowledgeable about football it seemed. Entire groups of fans telling folks around them cheer because the offense had an important 3 & Long. Just amazing.
I've been to a few different stadiums around the country for "normal" games" as well as some really important games with playoff implications, and rivalry. The fans at Jacksonville stadium (the few that showed up) acted worse than fans I have seen anywhere else. Very disappointed
