I think they take you to where the famous voodoo queen Marie Laveau is buried.
When we were there back in 1982, i don't recall us going to that grave yard. It's not in a great neighborhood.There are other cemeteries that may or may not be haunted, and in better areas.
I recall one that was very well kept, with large fancy monuments, but can't recall the name.
I think there is a bar called the Bucket of Blood.It's located in an old mansion.The place was once owned by a sultan.One day a sultan appeared and he purchased a mansion that was for sale. Son his harem girls and body guards arrived. All went well for the sultan and his staff, until one terrible night,when all were killed.
In the morning, some passersby noticed what appeared to be a red liquid running out the door.Someone releazied it was blood, and they went for the police. What the police found was a bloodbath.Blood and body parts all over the place, like the people had been hacked to death.The body of the sultan was later found outside the house in the garden.
Nicholas Cage owns the Lalaurie House. He was on Jay Leno,when Leno was still hosting the Tonight Show.It was an interview earlier ,back maybe April or May.Leno asked Cage about the house.Nick said that they did stay at the house, but not at night. Jay asked if he would let anyone investigate the house for ghosts, and Nick said no. Personaly ,I think that's a shame, as considering all the horrible things that happend to the Laulaurie servants,activity must be going on there, but from what Cage said, I got the impression he didn't want to exploit the misery these ghosts went through in life. However I still think it would be interesting to see what GH would get.
