Montana has them too---"boltholes," I mean.
Twenty, fifty, 200,000 acre mountain "sanctuaries," supposedly.
But if things do get really bad, the owners will have to employ small armies to defend them.
Let's say it might be a rich Bostonian hedge fund manager who owns the place, and the airstrip and the jet and the art and the vault in the basement of the house where he and his fat lazy children and his astonishingly beautiful wife take their refuge...
What I have to wonder about the captain of the private army---the roughest toughest badass in the land---is how long is that captain going to be willing to take orders from Mr. Boston and his snotty, spoiled, worthless children?
The lovely lady...well, that's a separate question. There's a reason they're called trophy wives.
You can employ other things that can multiply the force.
Gas is the easiest, if your safeguards are in place.
You can range it from debilitating type gases to lethal, and if you choose right you don’t pose any ongoing risks to yourself or your family.
Livestock is another matter. You can defend yourself with very few, or no, people. You just need to have the means and the will to use the system, and use it without exception. That takes a touch of sociopathy to pull off.
You have accurately summarized the defects in this “bolthole” strategy...
If “safety” in the coming insanity is what they seek, this ain’t it...
