I am not sure about any of those, but I know the only graffiti I am okay with are the Pictographs and Petroglyphs left by early inhabitants of our region. I have not been to it, but I have seen photos of several areas around Petit Jean State Park in N/W ARK. have painted glyphs. The only ones I have seen in person were at Thousand Hills State Park in Kirksville MO (N/E MO) when my wife attended school up there. It does bring up the question as a history teacher, are these art or grafitti? (BTW-I think they are both).
