Crossing a bridge
William "Doc" Carver "invented" horse diving exhibitions. Allegedly, in 1881 Carver was crossing a bridge over Platte River (Nebraska) which partially collapsed. His horse fell/dove into the waters below, inspiring Carver to develop the diving horse act. Carver trained various animals and went on tour. His son, Al Floyd Carver, constructed the ramp and tower and Lorena Carver was the first rider.
