The Houston Livestock Show and Rodeo, also called RodeoHouston or abbreviated HLSR, is the largest livestock exhibitions and rodeo in the world. It includes one of the richest regular-season professional rodeo events. It has been held at NRG Stadium in Houston, Texas, since 2003. It was previously held in the Astrodome. It is considered to be the city's "signature event", much like New Orleans's Mardi Gras, Dallas's Texas State Fair, San Diego's Comic-Con and New York City's New Year's Eve at Times Square.
