On This Day in 2016, I completed my goal of Visiting 100 National Parks in 100 Days to Celebrate the 100th Anniversary of the National Parks System.

I chose to end at Wupatki National Monument, which was one I adored as a small kid—especially the Wukoki ruin. I’ve since completed all 429 park units.
