US survivalists like to keep their preparations secret. They fear that their less well prepared neighbors might turn up on their doorstep and need to be shot. In fact I suspect that many of these secret squirrel types are a great deal more conspicuous than me. There is nothing as conspicuous as someone with a secret.
My motto is 'first do no harm' and this includes wasting police time. Acting like a potential terrorist through the promotion of wacky conspiracy theories and the stockpiling of potential weapons takes the police from the real bad guys.
If there is a crisis I am sure that my neighbors will come to me for help and I will either share my supplies or not. The fact that I run this website has nothing to do with it. Therefore.. there will be no secrecy whatever.
