I haven’t heard that the compound has been shut down so it’s still there as far as I know. One of the Nashville news stations sent a reporter there a while back and he got nowhere with it. He talked to the sheriff and even he didn’t know much about the place. Only that it was there. It’s tucked away, waaaaay back in the woods.
I’ll bet the sheriff would know everything about a prepper training base “way back in the woods”.
