Texas Prison Museum - Prison Rodeo HistoryThe Texas Prison Rodeo was launched in 1931 during the depression years, being first held at the baseball park outside the "Walls" Unit. The baseball park, located on the east side of the prison, was normally home to the Walls Tigers baseball team. The rodeo was the brainchild of Lee Simmons, General Manager of the Texas Prison System. Simmons envisioned it as entertainment for employees and inmates. Welfare Director Albert Moore headed up the organization and planning for the early rodeos along with Warden Walter Waid and livestock supervisor, R. O. McFarland.
