Ken Burns series on national parks repeats on PBS to celebrate National Park Service entennial

To help celebrate the National Park Service Centennial, PBS is rebroadcasting a six-part Ken Burns series on national parks. The series, "The National Parks: America's Best Idea," was filmed over six years at various parks. It is the "story of people: people from every conceivable background—rich and poor; famous and unknown; soldiers and scientists; natives and newcomers; idealists, artists and entrepreneurs; people who were willing to devote themselves to saving some precious portion of the land they loved, and in doing so reminded their fellow citizens of the full meaning of democracy," reports PBS.
