I have mentioned in several opportunities what I could have done better, given the chance. Here some of my afterthoughts about it. As good as your plan may be, you may have to leave it all behind. You must plan to be mobile.
Some of these preparedness plans may not work as well as we would expect. No matter how wonderful your retreat is, there may come a time when you have to leave. And you must plan for that, too.
A walled retreat may not work in the long-term
Building a large fortress could seem a very attractive idea. Stocking and piling food and other goodies is, for sure, an even better idea. But, unless the kinds of event you are preparing for be something like a zombie attack, or a deadly, fast, pandemic…it is not going to work very good. Because you will find knocking at your door desperate people that, after the first weeks, will be desperate enough for trying whatever they could figure out to take over the compound.
And I say this because I saw it happen. I made one acquaintance, a nice fellow, judo practitioner, combat shooter (back in 2006-07 you could still buy a gun and ammunition for home defense and sport shooting), with a nice, large, wonderful cattle hacienda (larger than a farm indeed, about 1200 acres, maybe more). He was pro-guns, had studied in the States, and generally, his mindset was not that of the average Venezuelan regarding self-sufficiency. His house there was surrounded by a tall wall. Bullet holes all over the upper edge indicated how many times he had to shoot to warn trespassers.
Food in a large pantry and a small wind/solar arrangement to power some HAM / UHF equipment for the security team of the hacienda was as well in place. And of course, a small pool, and a large water tank with over 25.000 liters. There is a lot of rain there, so this was not exactly a concern. However, the huge drought in 2008 taught us a lot of lessons about this.
The judoka farmer, had this little problem: his cattle losses were so high (and this was way before Uncle Nicolas) that even before the collapse, he had to sell his land at a loss, his wonderful big house in the suburbia, leaving just a small flat in the city.
I know, he could just have shot the guys. But obviously, those who think like this have not the slightest idea about how things are there. Shooting someone, even if this person is obviously trespassing and with intentions to do harm, is seen as plain murder…even if you are defending your own life. The reasons? Easy. Authorities are so…deviated, so to speak, that unless you have enough financial means to pay some… "contributions", the shooter won't leave prison. Ever. The only shooters I have seen that are still in prison because of the right reasons are a couple of drug addicts (father and son) who shot dead a family father in the middle of a drunk fight for a parking space in front of a liquor store. Cold blood, in front of his small kids. They locked them up and threw the key. One of my friends was there.
