Growing up on the Front Range of Colorado in the 1960s, David's family spent summer weekends west of Denver. Walking along the Colorado Central railroad grade between Georgetown and Silver Plume, his grandfather pointed out the large rock abutments of the long-gone high bridge on the Georgetown Loop. Thus began a fascination for "what was there before."David moved to the Gunnison Country to attend Western State College (now Western Colorado University) in 1978. After graduating and beginning a career in technology, his avocation was focused on researching the history of the Gunnison Country. He has presented historical slide shows, conducted tours, and helped produce a GIS (Geographic Information System) database and map of historic sites in the Gunnison Country. Based on his grandfather's stories of growing up in Steamboat Springs in the early 1900s, David researched and wrote the book, Steamboat Springs: Memories of a Young Colorado Pioneer. He was a member of a team contracted to research, write, and publish the book Medicine in the Mountains: The Remarkable Storied History of Health Care in Lake City for the LCMC Endowment Fund, Inc. David has served as a long-time member of the Gunnison Historic Preservation Commission and as a board member of the Denver, South Park, and Pacific Railroad Historical Society.
