Las Vegas is all in on a mystery nobody can solve. A cryptic golden emblem paired only with the date July 16 has suddenly appeared on digital billboards and displays across the Las Vegas Valley, sending locals scrambling to place their bets on everything from aliens and secret societies to a major sports reveal. The unexplained campaign has surfaced at the Park MGM, Fontainebleu, Circa, AREA15, the Smith Center, Water Street Plaza, UnCommons, Tivoli Village, the District at Green Valley Ranch and other locations, according to the popular RealVegasLocals social media account. The display offers virtually nothing for amateur sleuths to work with.
