Could ‘What happens here only happens here’ be the new tourism mantra of Las Vegas? Ed Komenda, Reno Gazette Journal · December 3, 2019 at 1:08 pm LAS VEGAS – “What happens here, stays here.” For almost two decades, those five words have served as this city’s motto of excess. Rarely has an official tourism slogan been so widely recognized, with travelers often reciting the familiar “What happens in Vegas, stays in Vegas” mantra. The catchy and controversial one-liner encouraged and empowered tourists to behave in ways they would have never dared back home – a wink to the naughty. But there have been rumblings along the Strip that that slogan may soon change to something a little different.
