Just FYI, my wife and I got into a couple of doomsday movies last weekend and one on Amazon Prime turned out to be pretty good. It was made in 1962 and stars Ray Milland, I think it is called Year Zero. It was released shortly before the Cuban Missile Crisis. So the cool thing is that so many of the prep stuff in there is practiced today, and the main character (Milland) seems really well versed in what is needed but without being a prepper, he just uses common sense and maybe some prior military knowledge, although it doesn't say he ever served in the military. Check it out if you get a chance
