We had a group of 8 plus Jessica, our guide. Jessica started by showing pictures of "orbs," "wisps," a form of ectoplasm, and actual figures captured in photographs. We were advised to take a lot of consecutive pictures and see if differences showed up between frames.
The real interest was in the historical stories of Chattanooga Jessica told. Murders, hangings, heart attacks in brothels, Civil War stories, Tiffany glass windows in a church. That was a great introduction into the depth of history in this city in the middle South. Jessica had a great upbeat spirit (har!) and really livened up the tour.
The tour was about 90 minutes long, and was an easy walk up and down a couple of hills. We recommend this for anyone who wants to see part of Chattanooga at night and hear about its spooky past.
