The Summit - Greatness. Ah..memories from the childhood. Reunion Arena and AA Center in Dallas: Mavs games were much more entertaining in Reunion. The crowd was more of a factor there. Atlanta: Can't think of the arena's name, but that place is an interesting experience. It's connected to a mall and office buildings, including CNN. Man, I wouldn't get anything done if I worked there. MCI Center - DC. Saw the Rockets and Wiz play there earlier this year. The MCI center sucks but the Rockets won. KT was amazing in that game.
Clearly you didn't attend much during the Ross Perot, Jr. days when the lack of a crowd may have been a factor. I've been to Reunion, the Hemisfair Arena (since torn down) and the Alamodome.
