Take a walk on the creepy side of North America's National Parks with retired ranger Andrea Lankford. Andrea shares such eerie tales as John Brown's haunting of Harper's Ferry, the disembodied legs that have been seen running around inside the Mammoth Cave Visitor Center, and the "wailing woman" who roams the trail behind the Grand Canyon Lodge. Lankford also uncovers paranormal activities park visitors have experienced, such as the chupacabra that roams the swamps inside Big Thicket National Preserve and the teenage bigfoot who rolled a park service campground with toilet paper. She also reports on long-forgotten unsolved murders, such as the savage stabbing of a young woman on Yosemite's trail to Mirror Lake, and the execution style shooting of two General Motors executives at Crater Lake. The witnesses to the supernatural occurrences are highly credible people-rangers, park historians, river guides, and the like-and each tale has factual relevance to the cultural or natural history of the park.
