 The Mirage vanished from the Las Vegas Strip. The tropical island-themed hotel and casino, complete with a volcano which erupted nightly, closed Wednesday after the last guest checked out. The Mirage was one of the earliest businesses in the building boom in Sin City. The property's new owners, which include Hard Rock International, will build a new guitar-shaped hotel with 600 rooms. Back in April, another historic property, the Tropicana Hotel and Casino, closed to make way for a ballpark. Daria Albinger, ABC News.
