Houston has an extensive park system that includes Hermann Park, the home of the Houston Zoo; Memorial Park; the Armand Bayou Nature Center; and the Houston Arboretum and Nature Center. In 2000 the Houston Astros of major league baseball left their longtime home in the Astrodome and began play at a new outdoor stadium, Enron Field. The Houston Rockets of the National Basketball Association play at the Compaq Center sports and entertainment complex. Among the city's many annual events are the River Oaks Garden Club's Azalea Trail, a tour of azalea gardens at Bayou Bend and homes in River Oaks; Houston International Festival, a ten-day downtown celebration of the city's different cultures; and the Houston Livestock Show and Rodeo.
