This week on Inside Appalachia, a wildfire in 2016 escaped the Great Smoky Mountains National Park. It killed 14 people, injured dozens more and destroyed parts of Gatlinburg and Pigeon Forge. We talk with an investigative journalist who has new information on the incident. Also, four decades ago rice seeds from Laos crossed the ocean to California and made their way to a family of Hmong farmers in North Carolina. And the Appalachian trail has been exhaustively hiked, explored and written about, but it’s still got a few secrets left.
