I'm ready. I have Obese neighbors to eat, a swimming pool to drink, and duct tape.
Not I.
I prefer lean meat.
As for the OP, either I posted here or on a duplicate thread, but can't find either one, so...
Don't think it's going to happen. There are too many good, rock-solid people sprinkled throughout the entire collection of systems, from those who manage our electricity, water, gas, and oil supplies to those who grow our food to those who ship our critical supplies.
I know where most of them will be if the SHTF: Doing their jobs. If some of them turn yellow-tail bail to go hide in a hole, I know where I'll be: On-the job training.
Well-armed, of course.
