These kept popping up all over town, like cheap sneakers looped over the telephone wires; after a while, you didn’t even see them.
You would see them 8th and Hennepin, and on the overpass by the Berber District, and all up and down the Hammerhead Highway. Discreetly up on the walls of the Skybus between the ads for shyster lawyers and semi-accredited nursing schools. Some enterprising kid made a single-serve tumblr about it; others made a half-assed meme, put it on a t-shirt. Wasn’t viral, so people scrubbed their likes from it and deleted their feeds: The City moved on.
No one understood that it was a warning.
