Conor Knighton is a correspondent for CBS Sunday Morning. During the course of 2016, he visited all 59 U.S. national parks in celebration of the 100th anniversary of the National Park Service. At every park, he stopped and recorded himself singing “America The Beautiful,” and made this compilation video in which you can get a glimpse of them. In this segment from the show, he tells us about his tour. You might want to enlarge this one, because the scenery is lovely.
