I'm not american, and i know what the hoover dam is.... how can you not? It's like, one of the most iconic man made structures there is.
And also, your mothman retort is terrible. How do you know there is mothman 'becauz yu dnt no that' It's simply not true. Just like sharks, just like leatherface, just like piggsy, just like the epsilon cult HW, just like aliens, just like bigfoot, just like the birds in the rocks, just like the great flood bullshit. IT'S ALL BULLSHIT. Fuck sake.
