National Parks Traveler: Hiker Trash, Fishing Great Smoky Mountains National Park, And "Acting" Directors

"Hiker Trash," a new book that examines hiker life along the Appalachian Trail through the sketches of a graphic artist, is the topic of our interview with author Sarah Kaizar. We also look at the fisheries of Great Smoky Mountains National Park, and comment on the long-running vacancy of a permanent director of the National Park Service.
