John Mueller is a founding member and current board member of Busses of Yellowstone Preservation Trust in Red Lodge, Montana. He has studied and researched the history of the Yellowstone Park transportation system for over 4 decades. John has hands-on experience on woodworking and sheet metal fabrication. This expertise has been used in the preservation and restoration of several Yellowstone Busses, and has led to a life-long interest in Yellowstone Park transportation history. The presentation will cover the transition from horse-drawn to motorized transportation- “Horses are out, motorized vehicles are in!”
