Hey, I’ve been there! Really weird place out in the middle of nowhere. I always recommend people check it out if they’re in the area. Not much to see, but it’s a good way to kill some time.
I just visited there a couple months ago - there's a small camera mounted on a pole about 10 meters from the structure. If it's not a national or state-maintained monument, then who's monitoring this feed?
I can't imagine how pissed off I'd be if I survived a nuclear winter and traveled hundreds of miles to read the prophesied guidestones that could save us all, only to find out that they had several weird eugenicist rules but zero information about like, water purification or animal husbandry.
