i think its also a very good symbol of how the US just forgets about even their very own laws at a snap of a finger and that no nation in the world (not even the us itself) can ever trust them with anything. like for example the so called freedom of religion when we're at the Sioux Blackbhills anyway.
You have to park in a garage and walk down a narrow path lined with people trying to sell you shit. Its more like visiting a mall with aggressive salesmen than a national park. It was the worst stop I made during a cross country road trip.
