San Antonio Stock Show & Rodeo Ranch Rodeo Followed By Clay Walker is a night of real working-cowboy action at Frost Bank Center in San Antonio. Six hand-picked ranch teams of five cowboys each compete in timed events like steer loading, calf branding, roping and wild cow milking, all for the title of San Antonio Ranch Rodeo Champion. After a short intermission, country star Clay Walker takes the stage for a 60 to 75 minute concert.
