This was to have been an expose on billboards in San Francisco, at once an invective against their placement in a picturesque landscape and the manner in which they prove ideal canvases for Situationist actions. Along the way, we chronicle a heartwarming tale of NIMBY struggle, 21st century capitalism, and ornery Preservationists. But upon reading the signs, priorities changed.

The first one, at a service station on 8th Street, the second an awkward block away from The Stud. Why were we not previously hipped to this earlybird end of the world business?

Alright, we get that the world is ending. So put that on your calendar. If the world doesn’t end, there’s an excellent chance that you weren’t listening to AM Radio and there’s plenty of time to hoof it down to Guatemala and greet Quetzalcoatl’s fiery return. If the world does end and you’re left behind in the ensuing Rapture, start calling dibs on the RVs of the Saved. I hear some of those things got dishwashers.
