The tour itself is definitely a five. Jim is a 10. We came for history, and we got it. Not only did we receive general knowledge, but Jim answered all of our random questions, with more facts. His range of knowledge was impressive. He even went above and beyond, by offering his personal cell in the event we had questions later in our trip. Our tour group size was 6, which was perfect. Since this was a walking tour, we were exposed to things you wouldn't have seen on the typical "Charleston carriage" tour. This is a must do, when visiting Charleston!
