When I was in college in Florida, I took a trip to NOLA with a few friends and we took a day of the dead tour around Halloween. It was the creepiest thing I have done, but it was completely worth the experience. New Orleans is such a mystical place anyway, with all the voodoo and hoodoo legends that I almost felt like I could believe in some of the legends. The tour was in the middle of the night, and we went to the intersection of Canal Street, Canal Boulevard, and City Park Avenue. The hairs on my neck were standing straight up the whole time. At this very intersection, there were 17 different cemeteries at one time, and it is the likely starting point for the Search for the Gates of Guinee.
The legend of the Gates of Guinee basically states that there is seven gates to the land of the dead guarded by seven separate guedes. Baron Samedi, a powerful spirit who is the gatekeeper and collector of souls, leads all of these Guedes. It is an amazing story, and anyone interested should look it up.
