Documentary filmmaker Ken Burns has done it again. On Sunday, September 27, The National Parks: America's Best Idea, his most recent series, will debut on PBS stations. Jim Axelrod interviewed Burns for Sunday Morning.
A new book also takes a look at our National Parks. The Wilderness Warrior: Theodore Roosevelt and the Crusade for America by Douglas Brinkley reviews the naturalist achievements of President Roosevelt, who preserved more than 230 million acres of American wilderness.
