Over 3000 people visited Townsville on the weekend of 5-6 May 1934 for the Mt. St John Rodeo. Flinders St was lined from both sides as the equestrian parade, led by the Townsville Railway Band and Rodeo promoter Mr. St. John Robinson & champion American rough rider Frank Maynard. Approximately 200 horsemen, horsewomen, girls and boys were in the parade.
