Marcia Franklin talks with Isabel Wilkerson, a Pulitzer Prize-winning journalist who devoted 15 years to researching and writing "The Warmth of Other Suns," a book about the Great Migration of African-Americans from the south to other parts of the country. The two discuss the reasons for the migration, its influence on the country, and the effect that the success of the bestselling book has had on Wilkerson's life. The interview was conducted in Idaho Falls, where Wilkerson was the keynote speaker for the Idaho Humanities Council's Distinguished Lecture there.
