I have changed many of my friends to either/and: 4×4 offroading, sport shooting, hunting. I have 2 now doing all, 1 in a few weeks doing all, several either sport shooting or hunting. And if you start real talking after a few beers, they all admit that they think that something could go wrong. They are no preppers, but at least they have quite good skills to “use” them after SHTF. There are imho no other ways in Germany to find other members for the “group”.
