Yeah, I read the whole thing, mostly going "Naw, I'm not doing that" or "How could anyone be so DUMB??"
But the part about having lots of things boxed up, untested... yeah, that's true. I've been buying things for twelve years - sometimes even having them shipped up there (to a friend's house) instead of to Virginia. One guy who bought me a big chainsaw laughs when I see him. He's gone through two or three chainsaws in the time since then, and mine's still in its box!
I've got almost everything I could think of that could matter in an emergency and be reasonably stored long-term in a garage. Clothesline, spools of polyurethane, fertilizers, motor oil, kerosene lamps, propane... it goes on-and-on. Three extra-deep garage bays are almost full, floor to ceiling. I really need the barn. My wife may not be as tolerant of it all once she has to actually live with it!
Prepping ain't a small task since there's no telling what might go wrong. It takes an incredible amount of space just to store what you might need for one type of crisis! Trying to get ready for an economic calamity, a nuclear war, a nuclear winter, a conventional war, an epidemic, an E.M.P., a supervolcano, an ice age, an asteroid, comet or Hillary-butt strike, etc is too much.
So I've filled up my place with a bunch of mostly-unopened boxes, just trying to get ready for one type of disaster. Now I'm reading that it's a bad strategy? Great. You can't win around here.
