Been to Knoxville. 40 years ago without going into Nashville IIRC Whatcha growing over there that you don't tell us about. Got to see the two faces goat and a few other freeks of nature. The ride of death inside a large barrel type of thing that the motorcycle traveled horizontal inside that thing. I'm sure we went there for another reason, but that carnival is all I remember.
Around that area is the mechanized army command with the Federal Gold, Fort Knox
If I find a map of Tennessee, like in Iowa it may help googled crew get me there without reaching for the cricket fine.
