I paid $1400 for a single ticket in the lower level endzone section, 20 rows behind the goalposts, for the 2006 National Championship game between Ohio State and Florida in Arizona. No regrets at all.
The game certainly wasn't the breathtaking back and forth as was the previous year's game between Texas and USC, but that wasn't the point.
Had just returned from a stressful deployment to the Middle East and had the cash to burn. And as a kid transformed into a Gators fan living the early 90s in Florida, where after watching Saturday morning cartoons, my grandpa would take over the TV, flipping on Spurrier's Gators teams, it was a more than unique and memorable chance to see my team win a championship. To this day, whenever I'm watching a championship I never have to guess what it's like to watch your team win it all. In person or otherwise.
Sure helps to balance out all the bad Arizona Wildcats football I've suffered through since soon after becoming a student at the University of Arizona.
No regrets it all. Still have the lanyards, game programs, and souvenir cups that came with the ticket. If you're a Michigan fan, $4000 for ticket(s)/flights/hotels would be worth seeing my team in a National Title game. That last Michigan Rose Bowl/Championship was 26 years ago.
