The first Pioneer City Rodeo was held forty-three years ago on a baseball field in Leaverton Park. The old wooden seats purchased then held only about 3,000 spectators and the ball field lights provided illumination for the night performances. Prize money that first year was $1,500.00. After two successful years, the Pioneer City Arena was constructed. The newly developed Super Sports Lighter Floodlights were installed and to this day no better lighting has been found. The purse that year was doubled to $3,000. Since that time, several improvements have been made to the Pioneer City Arena. Additional ground was purchased increasing the parking area. The old wooden seats have been replaced with aluminum seating providing room for more than 6,500 fans. The campground area has been added for the convenience of the fans and a few years ago, showers and new restroom facilities were added.
