Location
City insight: San Antonio
San Antonio is the second-most populous city in Texas, located in the southern part of the state and serving as the county seat of Bexar County. Its name, Spanish for Saint Anthony, was given by a Spanish expedition in 1691, and it had 1.43 million residents at the 2020 census. Summers are hot and humid with mild winters, so spring and autumn are the best seasons to race.
