It is interesting what you wrote. In the back of my mind, I know the limiting factor for enduring longer will be water.In a true SHTF situation the line blurs between the good guys and the bad guys. If you don’t think you have to become a bad guy to survive, you need to flush out your headgear.
And if you take what I’m saying, literally without truly understanding it, you have some research to do.
I have long thought that once the event starts rolling, I am going to hit the local Culligan shop in my rural community and gather as much water jugs as I can fit in my SUV. A "good" person doing "bad".
