^^ ZING! One for Scotty!!
That is the type of place I would build for myself, on a smaller scale, if I ever hit the big lottery. Controlled, indoor climate for long distance shooting?
The ability to get your rifle dialed in to the absolute gnat's ass and then only have to worry about windage and mirage?? And both of those you could build in elements to the indoor range to simulate??
That would be amazingly helpful in training shooters. I could pimp that to law enforcement agencies around the country for entry level sniper programs and have it booked out 6 months in advance.
Oh yeah, that is hella cool.
