About The Centennial Journey

The Journey

After making it a goal to see all 400+ parks managed within the National Park System, David visited over 150 parks a year in 2014 and 2015. He had visited over 300 National Park units by 2016, the National Park Service’s centennial year. David celebrated the centennial by seeing as many parks as possible among both the ~100 unexplored parks and those previously visited, all while maintaining a full-time job. By year’s end, his travels covered 146,000 miles to 387 NPS sites in all 50 states.

With 23 parks left to visit at the centennial’s conclusion, David completed his goal to visit all 417 National Park Service units with his visit to Reconstruction Era National Monument on the weekend of his 47th birthday in December 2017.

Note: The National Park Service currently has 433 units. As of September 2025, David has visited them all. New units since the book’s publication include Mill Springs Battlefield National Monument, Eisenhower National Memorial, Ste. Genevieve National Historical Park, Medgar and Myrlie Evers Home National Monument, New Philadelphia National Historic Site, Emmett Till and Mamie Till-Mobley National Monument, New England National Scenic Trail, North Country National Scenic Trail, Ice Age National Scenic Trail, Amache National Historic Site, Blackwell School National Historic Site, Springfield 1908 Race Riot National Monument, Carlisle Federal Indian Boarding School, and Frances Perkins National Monument.
