Sounds like you had a good time! What I'm trying to point out is that when the tournament is in Greensboro, they use the convention space to have the Fan Fest that goes on outside of the tournament venue, and they promote events at the ACC Hall of Champions Museum, they have country music concerts, and make the whole experience a family event with entertainment that is in addition to the basketball games. The ACC Hall of Champions Museum is basically a Museum of the Conference. It's next to the Greensboro Coliseum Complex.

The league basically celebrates itself when it has the event in Greensboro. The larger cities don't really do that. They just have the tournament. The advantage of the cities is the larger media presence. That has value. So Greensboro shouldn't be the only place to have it, but it should be on the rotation IMO.
