I’m pursuing the end of the world petroglyph idea and as part of a working trip to Wisconsin visited the only publicly accessible ones in the state. I had just read an essay in The Believer about young college men being drowned in some kind of smiley face cult conspiracy and then right before I came upon the glyphs there appeared a really frightening piece of smiley face graffiti. Lucky I’m too old to be caught up in the Zeitgeist!
