If people want to learn how to be prepared for what ever can go wrong in the future, they should sign up for Selco’s SHTF school.
I do guide people daily into learning self defense, upgrading their security, being aware of what is happening in their area, growing a vegetable garden… You do not always need to experience something bad before you realize you need to be prepared. I think you only need to look at the international news.
Some people will feel the need to do something. And How can this carry on?! But there is a place and time for everything. A time to warn and a time to be quiet. Tweva’s reply is spot on.
But I do think it is wise to advertise. My survival instinct tell me to stay away from the crowds. Do not let yourself stand out. Just do your thing without attracting attention. And that’s a skill as well.
