I bet he's a prepper…
In a previous life, I worked in aerial reconnaissance, specializing in identifying nuclear missile installations.
I'd say that's no fallout shelter. It's a missile silo.
Compare it with the attached photo taken in Cuba in the early 1960s.

Same thing happened all over the US in the 60's…
More like what was happening all over Cuba in the 1960s. I would suggest this guy isn't seeking to hide from a nuclear attack. He's looking to retaliate.
If pesky local town planning officials come knocking, he can always swat them down with the Second Amendment. And common sense suggests don't annoy the guy with the nukes in his backyard.
