"I've written whole songs on dog walks," says Amy Ray of The Indigo Girls.  "I write a lot when I'm on the lawnmower, says H.C. McEntire. What a great time this was listening to these two friends and fantastic songwriters go deep into their songwriting processes. For Ray, it involves writing five times a week for no more than two hours a day. For McEntire, it involves cork boards. We also discuss our shared love for Anne Lamott and Sharon Olds.  Catch them on on tour together this May.
