Have you been the the tourney? I went only once. Back before they had this great venue. Sioux Falls is a great place for it. If they had it in Grand Forks....nobody would show up. Sioux Falls is a pretty good spot. Easy drive from Omaha, KC, Fargo, Brookings, Vermillion. Probably an easy drive for a lot of the parents. Can plan it out wayyyy in advance.
Its a fun atmosphere down there. Yeah its SDSU heavy but that is an easy sacrifice to make to have a good atmosphere at the tourney. Imagine a conference tourney in Macomb or Grand Forks or Fargo....it would be an absolute joke.
