Las Vegas, New Mexico, is 70 years older than the Nevada city of the same name. Eleven years after its founding in 1835, it was the first settlement in Mexico reached by invading US troops in the Mexican-American War. In later years, it was an intensely violent place, an equal to Dodge City and Tombstone. Gunmen such as Billy the Kid, Mysterious Dave Mather, Doc Holliday, and others walked the streets of Las Vegas. The town also built grand houses and mercantile buildings. It rivaled Albuquerque and Santa Fe for importance and boasted one of the state's two streetcar systems. Here, Teddy Roosevelt announced his availability to serve as president, and Tom Mix filmed his earliest movies.
