Since Michael's commenter is broken, here's my response to his Chattanooga to surpass Knoxville? article.
Knoxville has the world's largest disco ball (the Sunsphere) and UT, which not everyone follows. The IMAX theatre and Aquarium in Chatt-town sure sound a lot more enticing than Knoxville if you ask me. Not to mention, Chattanooga is closer to Atlanta.
