San Antonio ( /ˌsænænˈtoʊni.oʊ/) is the seventh-largest city in the United States of America and the second-largest city within the state of Texas, with a population of 1.33 million. Located in the American Southwest and the south–central part of Texas, the city serves as the seat of Bexar County. San Antonio has a strong military presence—it is home to Fort Sam Houston, Lackland Air Force Base, Randolph Air Force Base, and Brooks City-Base, with Camp Bullis and Camp Stanley outside the city. San Antonio has a diversified economy with four primary focuses: financial services, government, health care, and tourism. Located northwest of the city center is the South Texas Medical Center, which is a conglomerate of various hospitals, clinics, and research and higher educational institutions. The jewel of the city is the River Walk, which meanders through the downtown area. Lined with numerous shops, bars, and restaurants, as well as the Arneson River Theater, this attraction is transformed into an impressive festival of lights during the Christmas and New Year holiday period, and is suffused with the local sounds of folklorico and flamenco music during the summer, particularly during celebrations such as the Fiesta Noche del Rio. Also based along the River Walk is the newly restored Aztec On The River, the only surviving exotic-themed movie palace in Texas. The Alamo, located nearby, is Texas' top tourist attraction, while the River Walk is the second most visited attraction. SeaWorld, located 16 miles west of downtown, is the number 3 attraction. Also, there is the very popular Six Flags Fiesta Texas. Morgan's Wonderland is a theme park for special needs children. San Antonio is home to the first museum of modern art in Texas, the McNay Art Museum. Other places of interest include The Woodlawn Theatre, the San Antonio Zoo, the Japanese Tea Gardens, Kumamoto, Brackenridge Park, the missions of the San Antonio Missions National Historical Park, the Museo Alameda, the San Antonio Museum of Art, the Witte Museum, the Texas Rangers Museum, the Buckhorm Museum, ArtPace, Blue Star Contemporary Art Center, SeaWorld San Antonio, Six Flags Fiesta Texas, the Texas Transportation Museum, and Splashtown San Antonio. Visitors can also experience something of the cowboy culture year round, they can see the 40-foot tall cowboy boots at North Star Mall. The city's only top-level professional sports team, and consequently the team most San Antonians follow, is the San Antonio Spurs of the National Basketball Association. Previously, the Spurs played at the Alamodome, which was built for football, and before that the HemisFair Arena, but the Spurs built—with public money—and moved into the SBC Center in 2002, since renamed the AT&T Center.
