I've never had a bad experience at Lucas Oil and have seen maybe 5 Colts games total since it was erected. They've always had decent music playing at the entrance to the stadium. The entire day is centered around the game, from the tailgating, to the bars and restaurants where fans gather to watch the game, to Touchdown Town outside of the stadium. Our most recent game was vs. the Seattle Seahawks back in September.
633 had decent seats considering we only paid $100 for two seats but the view was pretty bad as the photo above clearly shows. The players all looked small from afar so we felt a little out of the loop with what was going on.
The jumbo trons will be your best friend but in all likelihood, fans should avoid these seats and watch from home where the view is good, the beer is cheap and the bathroom lines are short. :P
If you can't afford good seats at an NFL game, hold out and wait until you can.
