Stay out of Centralia, PA! It used to be a nice little town with a coalmine, until back in the 60s, part of an exposed coal seam caught fire, and now the ENTIRE FUCKING MINE is burning. Yes, even now, 45+ years later. There's smoke coming up from sewer grates, streets that collapse, and all kinds of horrific awesome shit. My Environmental Geology professor said, and I quote, it "looks like Hades".

So, yeah, avoid Centralia like it has the plague, unless you want to fall through the street and end up in Silent Hill. Which I know you don't, because you're easily-terrified. ;p
