To the stadiums I have been to:
Top Tier
LSU - Night game, nothing like it. Absolutely insane
Texas A&M - Loud as hell and was fun
Penn St - The people were huge A-Holes, but the game was crazy loud and they hammered us that night
Washington - Cool area and was loud
Texas - Big stadium was loud and fun
Kansas St. - Decent setup and was pretty loud
Okie St - Just a great place to watch a game
Iowa - Not a bad setup. Wasn't overly loud, but that is what you get day after Thanksgiving
Oregon - Haven't seen a Husker game, but pretty fun stadium when I went to other games with my boss
Clemson - Fun as hell
South Carolina - Fun as hell, SEC is the best tailgating hands down
Mid Tier -
Oklahoma - Not really loud, but enjoyed the stadium and the people
Colorado - Love the stadium, but hate the people
Mizzou - Really hate the people, stadium is kinda meh, but saw some good games here
USC - A lot of bad seats and the people suck
Rutgers - My kids loved it and wasn't too bad. Small and was only about half full
Maryland - Same as Rutgers. Not on the low tier because my kids loved it
Minnesota - Nice stadium and easy to get to. Drank a lot of grain belts. Tailgating and gameday stuff sucks, but stadium was comfortable
Texas Tech - Had a great time, but was a kid.
Iowa St - Fun tailgating, that was about it
Air Force - Love their stadium, everything else is meh
BYU - Similar to Colorado. Beautiful area, but the Mormons were weird to watch a game with.
Low Tier -
Kansas - Doing upgrades for a reason
Purdue - Very meh, and they lose a ton of points because their turf blows
Michigan - Yes it is huge, that is about it
UCLA - Not sure why everyone loves this place. Horrible place to watch a football game
Baylor - Sucked
NW - Blows, but the new one looks nice
Oregon St - Reser sucks
