I dated a witch who lived in Salem. Not all its cracked up to be and I mean both the witches and the city.
I've been to Sleepy Hollow and Tarrytown at Halloween time and they were all hype - more fall harvest that you find in any small town than anything.
On the other hand, I'd love to hit up Dracula's Castle in Romania again. That place is creepy year round. Just avoid it when its cold.
I wish I could visit Demon's Alley here in NJ again. That was especially creepy for how the entire neighborhood seemed to have been abandoned at dinner time. But nobody can visit again, because arsonists burned all but two buildings and the local government tore down what wasn't burned.
I'd love to visit Jackson House again, another Jersey haunt, one where I photographed something creepy standing next to the broken player piano that still randomly played music, and I got chased through the house by a glowing blue orb. But again, arson, so nobody visits it anymore.
And Mary's Tower, which was haunted by something... animalistic. A lot of people who visited there with me always felt watched, like they were being hunted by something that was ready to disembowel them and eat their entrails before their very eyes before they died. Sadly, yet again, arson. And they place was nifty, too, like a little inner city tenement building, all by its lonesome in the middle of some farmer's fields.
The Mutter Museum is a nifty place, but avoid it if you suffer from claustrophobia.
Gettysburg would make a mint if they let ghost hunters from all over the country camp on the battlefields.
What I'd like to do is a New England tour of towns that were inspirational to HP Lovecraft.
