Lander, Wyoming's Pioneer Days Rodeo, established in 1894, predates the Cheyenne Frontier Days by three years. Initially hosted on the Bill O'Neal ranch with a ten-mile relay race, it moved to Ed Farlow's property in West Lander in 1900, where he built a grandstand and track. Farlow, a key promoter, along with his sons, enhanced the event's popularity, influencing the cowboy image on Wyoming license plates. By 1912, the event was known as "Rocky Mountain Round-Up Days." Various locations hosted the rodeo until 1934 when it settled at its current grounds, adopted by the Chamber of Commerce. Despite challenges, including the Great Depression and World War II, local tribes often saved the event, contributing significantly to its continuity. Today, continuing over 80 years at the same location, the rodeo celebrates Lander's historical slogan "where rails end and trails begin," maintaining its vibrant cowboy spirit.
