I have one... we don't call it a bunker, we call it a safe room, it's fire proof, so, we can go there for tornados, or if the house caught fire, & we couldn't get out... it's not bomb proof though, & while it has a ventilation system, it's also not radiation proof... it's 2 rooms, the back room with shelves for bottled water, & long term storage foods...
however, because we raise all our own meat, we have 4 freezers, one for each type of meat, & have a pantry, that holds a pick-up truckload of canned goods, organized on shelves, so we can easily pull a can at each meal, & monitor when it's time to restock... ( these are in the normal living area ) I've personally had to deal with preppers who died, before they needed their supplies, & seen the kids all throw it into the dumpsters, most was old, some was in forms the kids & grand kids wouldn't eat... I don't personally like stock piles like that... whatever you have, should be what you actually like to eat, and should be eaten out of every day, & resupplied as it's used... ( canned goods in a pantry, as opposed to dried 5 gallon buckets of food )...
we had one issue a couple years back now... during the big post covid toilet paper shortage... we always bought a huge case, that we pulled out of... of course when there was no toilet paper on the shelves anywhere, we had like 2 rolls left in the bottom of our huge case...
. His current underground garage project is a really fun watch as well. I bet his neighbors love him.
