Input: The first casino to be built on Highway 91 was the Pair-o-Dice Club in 1931, but the first resort on what is currently the Strip was the El Rancho Vegas, opening on April 3, 1941, with 63 rooms. That casino / resort stood for almost 20 years before being destroyed by a fire in 1960. Its success spawned a second hotel on what would become the Strip, the Hotel Last Frontier in 1942. Organized crime figures such as New York's Bugsy Siegel took interest in the growing gaming center leading to other resorts such as the Flamingo, which opened in 1946, and the Desert Inn, which opened in 1950. The funding for many projects was provided through the American National Insurance Company, which was based in the then notorious gambling empire of Galveston, Texas.
Output:
