The only thing I have to say about Rawles, is the thin veneer analogy.
That pretty much sums up when it will all fold. Take away the comforts of modern life like a flushing toilet, water from a faucet, heat or cooling, flipping a switch and the light and other electrical devices turn on and boom for the home.
No power also means most, if not all cannot work thus no paycheck, no bank transactions, you name it. And when those cell towers lose their fuel or phone batteries run out, oh boy watch how quickly modern life turns to the wild, wild west.
That is when your prepping comes to pay off and lock and load 24/7 perimeter security becomes one of your main job titles.
Thin veneer!
