Some friends of mine went to the games at Wells Fargo. They sat in front of some fans of other schools (Illinois and Arkansas). Those fans were blown away at how nice and big Des Moines was.
They also said that the Arkansas "Pig soowee" thing the fans did was weird and dumb.
Hopefully your friends had a better time than the corporate guys in the section right next to Illinois.
I have some connections so was lucky enough to be able to go down in the 2nd half of the Illinois-Arkansas game. We were right next to the Illinois side and about 5 rows behind Brian Anderson and Jim Jackson.
There was an entire couple rows of corporate guys in those seats that looked completely bored and uninterested in even being at the game.
Must be nice to get $1500 dollar sears then be bored. Meanwhile it was the best 45 minutes of my sports watching life. The atmosphere down there is so much different than any other part of the arena.
