Funny (true) story about that place. my mom and sister came up to Asheville to visit a few years back, and said they wanted to see that place, so we loaded up in the car and drove over.
As we were driving into the entrance, my sister, from the front seat, points over to the left into the woods and says, "what's that guy doing?". So I look, and there's a guy standing behind a tree in full Confederate regalia, holding what looks like a musket. He sees us, and goes running back into the woods. So I figure there's some sort of reenactment thing going on to coincide with the history there. Except when we started asking around about that, people looked at me like I had three heads. The lady at the ticket desk had no idea, and neither did any of the employees leading up to the house, or any of the employees in the house.
So basically it was just a crazy dude trying to freak out the tourists who were driving in, or ghosts are indeed, real.
