I live about 20 minutes from there -- it's a beautiful place.
I worked at the Lily Dale Post Office for a while back a few years ago. The people are very nice and quite interesting.
Had a reading there once; the guy got a lot right. It was a very interesting experience.
Do I believe in it? I'm not sure to tell you the truth. But after having worked around these people, I'm convinced that they believe in what they're doing.
I live near there too, never went there. These people are professional, they have a lot of tricks up their sleeves. That is why magicians like Randi and Houdini worked to expose them. They could duplicate practically all the affects without claiming one paranormal power. I am of the opinion that they are frauds and scam artists. They rarely subject themselves to scientifically controlled conditions.
