The National Parks: America's Best Idea by Ken Burns. This film series first aired on PBS in October, 2010 and is fantastic both in history and videography. DVD and Soundtrack are stunning. Can buy on PBS or Amazon.
To commemorate the the 100th Anniversary of the National Park Service, we enlisted dozens of our travel blogging friends to assemble a MASSIVE guide to all 59 designated U.S. National Parks. Check out our most epic post ever, on what Ken Burns called "America's Best Idea"!
