511 Travel Plans; Buffy Sainte-Marie; The Yellow Envelope

Singer Buffy Sainte-Marie discusses her new album of activist "Medicine Songs" and what they have to say about our place in today's world. Then author Kim Dinan tells the story of how she quit her job, sold her stuff, and set off on a three-year round-the-world adventure — inspired, in part, by a certain yellow envelope. And listeners converse with Rick about the special concerns involved in traveling to politically sensitive countries.
