Madden said the dome versus the Vikings in the 99 playoffs was the loudest he has ever heard a stadium.
I went to STL in 2002, yes after the bitter SB loss I wanted to see them in person.
It was so freaking loud it almost felt like it was effecting your equilibrium. And blurring your vision.
It was Week 2 versus the Giants.
I swear it was the loudest stadium I've been in for a football game, and outside of a playoff game or two when LeBron was with the Cavs on their way to the finals (I think his third year), and that's a domed venue with 20K people so it's smaller with a way lower roof and it felt as loud but I dunno. In that big stadium that amount of noise was noteworthy. Especially when the Giants were in the huddle and at the LOS on offense.
I've been to a a handful of games and many concerts in STL, DET, CLE, MILW, TAM, SWFL and other venues/games. Nothing has topped it.
