From purple mountain majesties to cities built on coastlines, American landscapes are as diverse as the people that inhabit them. How does our relationship to the outdoors define us as individuals and as a nation? In his new PBS show “America Outdoors with Baratunde Thurston,” comedian and civic educator Baratunde Thurston explores this question, uncovering America’s complicated and passionate relationship to the outdoors, both in rural and urban settings. He speaks with Jenn White, host of “1A,” about the ways in which our landscape shapes and reflects our American identity.
