I've been there a couple times, and I'm going this weekend too. Just like everyone said, the stadium is very nice ... except I sat real close once (like row 3) and it was kinda hard to see over the players on the field ... I didn't seem to have that problem at FedEx.
The fans are cool, and the traffic wasn't as bad as FedEx when I have been there. Just like Gmanc said, I parked away on some residential street for 20 bucks, and walked. Most likely the weather will be awesome, and a perfect day for football.
