The Texas Prison Rodeo was held from 1931 to 1986. The arena is located next to the Walls Unit here in Huntsville. The arena in the photo above was built in 1951 and is now being torn down. I ran a 3.1-mile loop around town this evening. My route included the streets around the prison and rodeo arena. Only about 1/4th of the arena is still standing. The rest is a pile of concrete, bricks and steel.
