re: Certain people act like the Superdome is one of the best sports venues.....

I would argue that the Superdome is the most historic and relevant stadium in all Americans sports right now.

Forget Lambeau Field- how many Super Bowls were played there? And theyve re-done it so much, it barely resembles the stadium that was there from the 1950's/60's. Same with Soldier Field.

Yankee Stadium is GONE. The Boston Garden is GONE.

The Rose Bowl plays ONE BIG game a year. The Orange Bowl isnt in the Orange Bowl anymore.

Wrigley Field and Fenway Park are mainly baseball-only venues- and the Cubs havent played a World Series since the 1940's.

Here's a short list of some of the important things that have happened at the Superdome since 1975:

Pope John Paul II Papal Mass
Frank Sinatra, Prince, Rolling Stones, Michael Jackson, and every other huge musical act
George Bush "Read My Lips No New Taxes" 1988 RNC Convention
Super Bowls
Final Fours- including Michael Jordan's UNC in 1982, Indiana's epic last second win in 1987, and Chris Webber of Michigan calling a timeout he didnt have in 1993
Sugar Ray Leonard vs. Roberto Duran "No Mas" fight
Muhammad Ali vs. Leon Spinks rematch
Wrestlemania!!!!
Sugar Bowls
CFB National Championship Games

These are just off the top of my head-there's loads more.

What currently-used American venue can come close to this for importance, history, significance, and relevance?
