Here is an example of what you should not do, buy into or build yourself: A Hell Hole In The Ground
It’s kinda scary when you consider how many people are falling for this kind of ‘plan’ for their so-called “preparations”. They’re seriously doomed to fail because they’re simply piling greedy, rich people on top of each other in a survival situation. Not what anyone needs to survive calamity.
I’ve always advocated against this and still do. Armed guards notwithstanding, money and privilege and power doesn’t mean a hell of a lot when a serious crisis arises. They’re just as likely to discover that they’re asses get tossed outside of these hell holes by the owners / guards as soon as it is determined that they’re no longer needed.
But more importantly, other then showing up with a fistful of money, the individuals buying into these hell holes are not equipped to survive. They’re dependent upon everything else being done for them. The “Survive on the Dollar” theme is factually worthless in collapse or any crisis of significance.
There are also many isolationist ideas like this that will also fail when they’re broken down, attacked or suffer internal strife or sickness. This too is the primary “plan” and theme of the “prepper” crowd that is currently in place. Every man, woman and child for himself. It’s a stupid idea and will make for a lot of easy targets, breakdown and failures. The Triple Ought (Grey Nineties) theme (James Rawles) writ large (and wrong).
I’ve come up with something quite different then this, having studied this issue for some time.
Avoid the Hell Holes. There is something better.
