Sometimes there are clear reasons why a town is deserted. Perhaps it was a natural disaster like a drought or a flood. There may have been a man-made event, like a chemical spill. Maybe a once thriving economy dried up. However, sometimes it’s not always obvious why a place is deserted. Take Centralia, Pennsylvania, for example. You would never know from driving through this mostly deserted small town that a Hell-like inferno is roaring beneath the streets. The fire was started in 1962 and is expected to continue for centuries.
