The Astrodome in Houston was the very first domed stadium in the world. The Houston Astros played here until they opened their new stadium downtown. The Houston Oilers played here until they moved to Tennessee. The biggest event in the Astrodome every year is the Houston Livestock Show and Rodeo. The biggest rodeo in the world comes to Houston for two weeks every year. More than 50,000 people go to the rodeo each night. All the major country music acts perform at the rodeo.
