I am fascinated that this thing was not full of water. I’ve seen quite a few stories like this one and invariably the shelter has filled with water over the forty-plus years of being ‘lost’.
I used to know a guy who had a shelter similar to this kind buried in his yard under his patio. He wasn’t really expecting a nuclear exchange (or maybe he was and just didnt tell me) but he did say that it was where he would keep all his valuable guns and stuff in case a forest fire came roaring through his little patch of nowhere.
I’ve no doubt there are plenty of these forgotten shelters out there. One of special interest is a ‘demo model’ of an underground house built for the worlds fair back in the 60’s. Some folks think it’s still there and want to go digging for it.
And although techincally they arent as dramatic, every so often impromptu public fallout shelters are discovered stacked with mountains of ancient Civil Defense gear.
Like those pesky WW2 leftovers that keep getting dug up everytime someone digs a new subway tunnel in Berlin, these sorts of things will keep cropping up from time to time. I , for one, find them utterly fascinating.
