Ghost Adventures was pretty good last night - it was very touching and sad. They investigated a slave house built in 1825 in Maysville, KY. That's about 1 1/2 hrs. from here, up near Cincinnati. The owner had a slave jail under his porch and the house was later used as an underground railroad stop. The guys used the ghost box and after a while got some voices. They also used the device that a spirit can choose words to speak with. The voices were captured deep in the tunnels. Very cool.
