I will go out on a limb and say "Death Valley." LSU. Baton Rouge.
I was born in Baton Rouge in 1969, while my father was finishing his PhD. Taught there. Years later would get my MA there. At the time I attended LSU (early 90s) sucked. But to come to play "Saturday Night Under The Lights" was never something that was easy.
Now we are good and 98,000 folks (working on 106,000). Often hear it is the loudest place in the nation to play a game.
I assume things have changed, but not much. When I went to LSU it cost me $3.00 for tickets to a football game. I recall camping out for a week to be in the front row when we played Duke (those tickets were free). Shaq vs. Duke. Dale Brown, the basketball coach, sent us kegs of beer each night. Pretty sure that isn't allowed today.
LSU!
Try this if you need a primer:
And if you need help, well the Golden Band from Tiger Land drum riff.
I've seen college football games in many places. Kind of a thing for me. This is something almost religious to experience.
