Really enjoyed this tour with two groups making up a total of 8 people, half adults and half children. Our guide Jeff is a very interesting person and did an awesome job telling us about the history of the area AND making it fun for the children. Jeff provided "detection devices" that picked up electric fields showing the strength on a color coded meter, which went crazy at a couple of the graves and spots along the tour. Since there were no electric sources in the area we can only concluded that we were in the presence of others.
