I think the much bigger concern would be getting there. In such a scenario where you need a 3 year food supply, I doubt the highways to get to where these things inevitably are will be usable.

The counter for this would be to relocate there earlier in the unfolding of a crisis, before most people have caught on, but then you'd have to go more often (lower relocation trigger threshold), and also stay there until it's over, which would mean you'd have spent ~all of 2020 in one.

Many people did that.

A friend sold his camp near Lake Champlain to some dude from NYC, sight unseen, for about $100k over asking in April. It was unwinterized, and the buyer dropped a fortune into making it a 4 season home.

This actually happened to a bunch of the rich people who, by the time they realized COVID would be a good time to relocate to their New Zealand apocalypse bunker, couldn't get flights out of the US or into NZ to get there.

I wonder how many are re-evaluating their location choice.

Honestly if I lived in the U.S. or Europe and I had a bunker I still wouldn't leave it now.

Probably. I mean, having 12 months of food and other necessities sounds pointless and then COVID happens and it looks sorta clever. The so-called "Reign of Terror" in France lasted about 12 months, that would be a really great time to have had a bunker stocked for 3 years.

We don't know what will go wrong. Being over-prepared and easily weathering difficulties is a much better plan than being underprepared.

yeah everyone ought to have 6-12 months of food in their house, and I’m not even Mormon

The question is always, unless your bunker is set for like 50 years of isolation, what are they planning to do 2 years later when nothing's improved?

Strongholds and regionalization are pretty much the worst responses to any crisis, seeing as how the entirety of this era of modern civilization traces it's origins to the rise of global trade that began in the renaissance.

I've been around enough startups to know I can just grab a shovel when the bombs fall.
