Having been inspired by the kindness and encouragement of park staff throughout the country, David wished to do more during his centennial celebration than just visit parks. He hoped to create something tangible as a “thank you” to all those who helped him on his tour.
While visiting a trail office in 2014, David noticed a framed collection hanging on the wall of rounded, triangular trail signs for the 30 trails in the National Trails System. Admiring the display, he wondered if it might be possible to do something similar for the parks.
In the summer of 2015, most park stores managed by the nonprofit organizations Eastern National Association and Western National Association, representing almost 250 locations around the country, began offering two sets of rectangular lapel pins themed for the Centennial and Find Your Park promotions. Each set features their respective logos on top and the park location on bottom. Collecting and framing a complete set of each pin style would be the project! David planned to offer these collections to the represented parks as a traveling exhibit before donating them to a permanent home in the parks.
There are 248 park locations across 46 states and territories represented among the 484 pins in the two collections. David visited all these locations in 2015-16 to collect these pins, most of them unavailable for sale on the internet. The 20-month project culminated in February 2017. In April 2017, Homestead National Historical Park became the first park to host the collections. They have appeared at fifteen parks or park-related locations as of February 2021. In addition to Homestead, the list includes Lewis and Clark National Historic Trail, Pullman National Monument, Indiana Dunes National Park, Cumberland Gap National Historical Park, Castillo de San Marcos National Monument, Eastern National Association, Steamtown National Historic Site, Dayton Aviation National Historical Park, Greenbelt Park, Cape Cod National Seashore, Vanderbilt Mansion National Historic Site, Fort Necessity National Battlefield, and Ulysses S. Grant National Historic Site.
Originally intended to only describe his centennial travels, David extended the story with several chapters covering the last 23 parks visited in 2017 to make it inclusive of all the NPS units, all the national trails, over 40 national heritage areas and about 15 affiliated sites. Following the events through 2017 also allowed David to share the outcome of his professional situation, as well as the exhibit he created for the parks.
