Is there something strange in your neighborhood? It's probably a druggie. But if its not and is perhaps other-wordly, you may want to look into the Fayette County Chapter of the Pittsburgh Paranormal Society. The Uniontown Ninja won't help you here. Well, he will, but it won't do much good.
They just had an investigation Sunday night but have not posted an update on it. Bummer. If you'd like to call 'em up Ghostbusters style, the number is 724-570-1180.
There are plenty of ghost stories in this area, though. They should have plenty to work with. As long as somebody doesn't start tripping on acid and call them about all the ghosts they're seeing.
