In an interview with the filmmaker Ken Burns of the documentary The National Parks: America's Greatest Idea, he is asked,
"Of all the parks, which made the most vivid impressions?
The first time I went to Grand Canyon my jaw dropped and then every subsequent trip it gets better and better. I’ve been back four or five times. North Cascades on the border of Canada is amazing because it’s wilderness, a tumble of glaciers, and I love Yosemite. The first major shoot we did for this project in the spring of 2003 was at Yosemite. I think that Yosemite is maybe be the most beautiful place on Earth."
He has visited every National Park in the country and other countless areas and he thinks that Yosemite is the most beautiful place on earth, that should speak volumes to everyone about how magical of a place it is.
