Jackson Gold's Gym is awesome. Open 24/7, has full HS line, powerrack, and heavy DB's, plus I get in free because of the hotel I stay in.
Mufreesboro Gold's is just OK-- it's more trendy/lightweight than useful. That seems to be the pattern with Golds-- Awesome or meh.
Went to another one in Murph that was pretty good awhile ago-- olympus? olympia?
