"Night Light" will be doing a special show tonight with host Mark Eddy. Author and historian RICK OSMON will be our guest for both hours, and documentary filmmaker LEE PENNINGTON will be with the three of us for the first hour as we discuss their upcoming appearances at the Ancient Artifact Preservation Society conference. Lee will be focusing on Kentucky's Spratt Site and its mysterious stone walls and cairns. With these two, we'll also hear about King Arthur being in America and the Brandenberg Stone, which Lee was featured analyzing on "America Unearthed."
