This week, Ohio's Hopewell Mounds were declared a World Heritage Site by UNESCO, joining the ranks of the Parthenon, Macchu Picchu, Chartes Cathedral and other international treasures. Today, as part of the first Hudson Valley book signing for "Sacred Mounds", we'll take a look at the history and mystery of the mounds and how they inspired Jim Metzner's novel. He's the producer and host of the "Pulse of the Planet" Radio series and podcast. Get ready for a reading, music, good conversation, and an amazing historical adventure!
