Sometimes I think the "best" preppers are naturally born to it. I've a friend who, although he would never call himself one, is probably the most effective "prepper" I can imagine. In this post, I'll call him "Rich".
First and foremost, Rich was born into a strong rural farming community that was the home of his, and many other local residents' families for many generations. His roots are very deep. He has a large number of children, grandchildren, and great grandchildren living in the area. He has countless friends as well, many of whom he's known for his entire life.
Like many of his neighbors, Rich has always been a part-time farmer, but he retired from a successful career as an engineer for General Motors. He has an amazing array of skills. He can repair almost any type of mechanical device, operate heavy equipment, and handle most of the building trades well. He raises crops. Until recently he hunted, and can can raise and butcher livestock. Rich and his wife raised their kids to be God-fearing Christians and most of them inherited their parents' values. They are all resourceful, self-reliant, industrious and skilled. Any one of them will (and does) unselfishly go out of their way to help a neighbor in good times or bad.
The community is close and in difficult times they automatically band together. The range of talent represented is very broad. Working together, I can think of very little they couldn't handle. But I don't know one of them who's given any thought to "prepping" - they're just who they are.
I greatly envy Rich. In a SHTF scenario, given a choice between a fortified bunker and Rich's farm, I'd take the farm any day.
