I think I told about a man I met once, who had a group of people that he worked with to help them be prepared. How it all started, I have no idea. I will call him Bob, although that is not his name.
Bob had a few properties in an rural area, in and outside a small city in south central Colorado. His group has regular meetups at his city property, but he has a developed property outside of that city, that only his family has been to. No one in his group has been there, for the sake of safety. His private property was developed by him, a now retired construction worker who had his own company including large equipment for moving earth.
I first heard of Bob when I would go to the LDS storehouse. I was asked more than once if I was in So and So's group? No, I didn't know the man. But one of the canning machines that you could check out from there at that time, was gone, probably for years, checked out by this guy, and used by his group on their meetups, canning their food.
Bob had had his group for a number of years, and had been putting up food with them, practicing shooting and other skills at all of those weekend get-aways. He put together a list of what was required of all of his people to have. He had had this list for years, and expected that all of his people would do this, and keep increasing their preps. Somehow, he got word, or realized that not everyone was following his protocol. (People probably thought they could depend on others in a SHTF situation.) He decided to do an unannounced visit to the families to check their in home preps. Many failed so badly, that they were removed from his group. They had failed his quiz. Preps that had been stored at the small city property was returned to each of those families.
Without figuring out ways to test people, and to keep testing them and pushing to find the weaknesses, we are all as strong as the weakest link in our group.
BTW, I met Bob at a Survivalist store. He gave me his card and visited with me. He told me about his set up and group. He gave me some recommendations, one being to have lots of salt for preservation purposes. He offered to come and evaluate my home and preps. I was really busy at the time, and never did follow up with him.
