This week we our conversation with Yellowstone National Park Superintendent Cam Sholly on the state of his park. We discuss efforts to greatly reduce the number of invasive lake trout in Yellowstone Lake, Yellowstone’s infrastructure needs, and some of the conservation projects park staff is working on. And we also voice Traveler’s position that the National Park Service needs to conduct an environmental impact statement, not a less rigorous environmental assessment, on plans to drill for oil in Big Cypress National Preserve.
