I am a skeptic, and do not believe in ghosts. The reason I go to ghost tours is because they often tell about the history of the place, and tell wierd stories. This tour just talked about all the ghosts that are around us, encouraged people to photograph the "orbs" and talked about times people have captures ghosts with their camera.
The history part of the walk was pretty weak, which is the only reason I went. I wouldn't recommend this tour.
