Tennessee? Wondering whats the best to go to - Knoxville? Memphis? Nashville? Chattanooga? Pigeon Forge? Gatlinburg? Would like to do the usual stuff u hear about - I wouldn't mind going to Dollywood (wherever that is) ? Wouldn't mind going to the Grand Old Opry (not that we're really into country music that much) and some of the aquariums down there.. We've never been to TN so any help would be appreciated. TIA.
