Movie Mountain, Tennessee?

Some dudes next door accosted me about my TN license plate when I was heading off to work this morning. One of them claimed to have all these relatives there and that he even once lived in the surrounding area. Well the conversation ended when he started asking me about Movie Mountain.

I really don't know what the hell it is. Mapquest reveals a Movie Mountain, TX, which doesn't even have a major road in its vicinity.

My first guess is Google's first result for the Movie Mountain adult film store. Yeah, there's lots of those in Tennessee. Just stop by Bucksnort sometime.
