Premise: The Hacienda Resort Hotel and Casino was a hotel and casino on the Las Vegas Strip in Paradise, Nevada, that operated from 1956 to 1996. It was one of a chain of four Hacienda properties, with the other three being located in Fresno, Bakersfield, and Indio, California. Each Hacienda featured a distinctive horse and rider sign; the Las Vegas sign is now prominently displayed at the Neon Museum.
Hypothesis: The Hacienda Resort Hotel and Casino operated for less than 56 years.
