What are the best sporting environments/venues you've witnessed first hand? Reason I ask, is, I told a friend (Illini fan) recently that Purdue/Mackey is right up there on the list and he laughed and said whatever, knowing I'm a Purdue fan - and he's never been to Mackey. A list of some of the more impressive venues I've experienced:
NFL: Green Bay is #1. I'm a Bears fan so it pains me to say it, but the atmosphere around Green Bay on game day is insane. Pittsburgh, when they were rolling was also a great environment.
MLB: STL has a good overall fanbase and stadium. I'm not sure that's my final answer, but it sticks out.
NBA: I've only been to a few stadiums, but the Bulls during the Jordan years were electric.
NCAAB: Purdue. My wife isn't a big sports fan, but she was a part of the orange crush at U of I during their peak years around 2005 - and she couldn't believe the atmosphere at Mackey and the Paint Crew's chants at the couple games I've taken her to.
NCAAF: Camp Randall/Madison is impressive, as was Notre Dame. I asked this question to a group of Big Ten officials at dinner a couple months back, and they each said Ohio State without hesitation and shared some great stories of just how loud it get's in there.
