I've been fortunate to have been to some of the classic games. I was there for the division clinching game against Miami in Dec of 1990, when the goal posts came down. That one was fairly loud. I was at the Houston comeback game in Jan 93 with my dad. By the end of the 4th quarter, even after a lot of fans left during halftime, that was the loudest I've ever heard it there. The Monday nighter against Dallas four years ago was very loud too. Wish I could've been there for this game but I live in WA state now. GO BILLS!
