We celebrate the Fourth of July by looking back at stories about one of the enduring features of our country: the land itself. This archive show includes an interview with Leland Bemet, who has studied ancient bison and bison hunting for nearly four decades. Plus, we speak with Jared Phillips about his book Hipbillies: Deep Revolution in the Arkansas Ozarks. And, we go to Crystal Bridges Museum of American Art where the Nature's Nation: American Art and Environment exhibit is on display through September.
