San Antonio is the second-largest city in the state of Texas and the seventh largest city in the United States. Located in South Texas, the city is a cultural gateway into the American Southwest. San Antonio is the seat of Bexar County with a population of 1,328,984 as of the 2007 U.S. Census estimate, as well as the 4th fastest growing large city in the nation from 2000-2006 in terms of percentage. Its metropolitan area has approximately 2 million people and is the 28th-largest metropolitan area in the U.S.

San Antonio was named for the Portuguese Saint Anthony, whose feast day is on when a Spanish expedition stopped in the area in 1691. The city 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 right outside the city. Furthermore, Kelly Air Force Base operated out of San Antonio until 2001, when the airfield was transferred over to Lackland AFB and the remaining portions of the base became an industrial/business park. The decision to close Kelly and consolidate its resources came from the 1995 BRAC. San Antonio is also home to the South Texas Medical Center, the only medical research and care provider in the South Texas region.

Famous for its River Walk, the Alamo, Tejano culture, and home to the SeaWorld San Antonio and Six Flags Fiesta Texas theme parks, the city is visited by 26 million tourists per year according to the San Antonio Convention and Visitors Bureau. San Antonio is also home to the first museum of modern art in Texas—the Marion Koogler McNay Art Museum, as well as one of the more successful National Basketball Association teams in league history, the San Antonio Spurs.
