I know of a few haunted places in South-western PA. It's kinda funny since both of them are also haunted attractions

I've played ouija at both locations and one does seem much more active then the other.
The first is Hundred Acres Manor in South Park, about 10 miles south of Pittsburgh. It used to be a pool before it was turned into a haunted house. One of the spirits is named Nicolas and he used to be a life guard there. He protects us from another spirit named Danny. After reading the stories on the site Danny reminds me a lot of Dug: hogging the board and is just plain rude.
Unfortunally, I've only gotten to play at HAM once and I truly doubt I'll ever get to play again. Danny follows my friend Tiny's board so he has gotten a rise out of me once or twice.
The other is Demon House in Monongahela, PA (20 miles south of Pittsburgh.) It's much more active than HAM. During a session we asked how many spirits were around us. The answer was 26! Ofcourse, the house has it's own graveyard even though the only marked graves are the original family's. I acted there during the July preview season and in my room I saw orbs. Tiny, who is also another haunted house actor, saw a little girl in my room. We believe this little girl is the original owner's daughter who died in a drowning when she was very young. One of my best friend's, Deanna, has seen the little girl in her room, which was right next to mine, numerous times. Other people in the house saw her downstairs in the kitchen, living room, and going up and down the stairs. I saw a man in my room and I did not get good vibes from him. I have a few stories from Demon House, both from direct experience and having other actors race up to me and gasp out "Did you see/hear THAT?!" Many other spirits have been seen.
P.s. I hope this doesn't sound like an advertisement, I wasn't trying to do that. But if you want to get your moneys worth, go to Demon House. The actors are better there and you have a greater chance of seeing the real thing! lol.
