1000 Yard Range Near Gatlinburg, TN?

Oak Ridge. Used to host military high power matches.

In central TN, there is Tullahoma? (Arnold AFB?) I forget the name, been 30+ years...
 
Dead Zero Shooting Park is the only one I know of that you can just walk in and shoot, but it is 3 1/2 hours from Gatlinburg.
Strategic Edge is members only unless you want to shot in one the monthly matches, and it is 4 1/2 hours from Gatlinburg.

I take it the wife has you going to Gatlinburg for vacation.
