First off, the ghost tours are For Entertainment Only! They are not a ghost hunting expedition, there is no expectation of ghosthunting equipment, and you are walking past PRIVATE residences or businesses so it wouldn't be cool of you to disturb the people if you did have any of that stuff.
These are just walking tours around beautiful old houses telling ghost stories with a little bit of history.
We took two tours with Lady Ravenwood. She is very nice, I recommend her. When she noticed some people in our party had trouble keeping up, she made every accommodation she could, including finding benches near the spots she was telling stories about so that the mobility challenged could rest. This is a NO JUMP SCARES tour, no theatrics, just good story telling in a magnificent location.
This is focused on storytelling. Most of the stories are based on the same rumors and speculation that you will find on most of the other ghost tours. Just remember that this is for Entertainment Only and you'll have a good time. However, if you do some fact checking afterwords, you will find some errors in the addresses, some stories that happened in three different locations would be attributed to a single house, some of the stories were debunked, some stories are plausible, but attributed to the wrong names and addresses. Just leave the skeptic at home and enjoy yourself, it's a nice walk, especially in the fall.
