Area 51

FILE – In this July 22, 2019 file photo, a sign advertises state route 375 as the Extraterrestrial Highway, in Crystal Springs, Nev., on the way to Nevada Test and Training Range near Area 51. A second rural Nevada county prepared Thursday for a “Storm Area 51” event that began as an internet joke but has drawn millions of social media fans. Organizers of the event hope people will gather and try to make their way into the once top-secret U.S. Air Force test area known in popular lore as a site for government studies of outer space aliens. An emergency declaration for Nye County took effect a day after county disaster preparation and sheriff officials told county lawmakers they’re unsure how many — or where — people might show up for events Sept. 20-22.
