I recently visited a town in Pennsylvania. Technically, it's no longer a town — because in Centralia, a fire has been burning since the 1960s. More precisely: beneath Pennsylvania.
An underground coal fire couldn't be extinguished despite years of effort costing 70 million dollars. The residents of Centralia were then expropriated by the state, the town razed to the ground, and what remains to this day is just a network of streets and sidewalks, the occasional fire hydrant. And the fire, of course. Somewhere down there, beneath the earth.
