La Playa Trail is the oldest commercial route in the western United States. Countless moments in the history of San Diego happened along it. Seventy registered historic sites have been identified on this trail. In this 1934 document San Diego Historical Society requested the permission to place a marker honoring explorer and trailblazer “Jedediah Strong Smith”.  He explored the Rocky Mountains, the American West, and the Southwest during the early 19th century. Jedediah S. Smith first set foot in Old San Diego in 1827.
