Las Vegas, where the party never ends, prepares for its biggest yet: Super Bowl 58

Las Vegas is about to throw its biggest party yet. Doors open Sunday at Allegiant Stadium for the city's first Super Bowl. Las Vegas is primed for an estimated 330,000 visitors this week leading up to the San Francisco 49ers taking on the Kansas City Chiefs. Even the Las Vegas Strip looks different, with Roman numeral installations springing up and a towering Vince Lombardi Trophy outside the Bellagio. One county official says the city's transformation for the big game proves Las Vegas has arrived as a sports entertainment hub.
