I will share my experience. I knew it was going to be this way, so I did indeed prepare for it. And overall, I had no problems with it.
-Got to tailgate at 7:30
-cooked brunch for the crew on my small charcoal grill
-headed towards the stadium at just before 11:30
-took a bit to get in, but I chose one of the better lines.....was in my seat with about 15 minutes to go on the clock
-my son chose to wait in line for beers (better him than me) but he made it to our seats with probably 5 min to go
-I got a pass out at half time, high tailed it to my car in the grass lot reserved for a couple of quick beers and high tailed it back. Got back in my seat with 14:56 on the clock. Missed the kickoff, that went into the end zone (so didn't miss anything, I've seen kicks before)
-stayed for about 5-10 minutes after 0:00 left the clock, cheering the team until they were off the field (mostly)
-knew it would be impossible to get out and on my way back to Indy. So, fired up the charcoals and cooked burgers, brats and dogs for the crew, while watching the 3:30 game on our tv
-packed up and headed home at about 530
I have no issue at all with how they handled the sell out crowd. Sure, hopefully they can make some adjustments, but I enjoyed the experience immensely.
