Early Friday morning — ahead of Alienstock, the music festival in Rachel, Nevada, that was organized after the viral Facebook event to storm Area 51 — a group of around 75 to 100 sign-wielding alien hunters gathered at an entrance to the mysterious U.S. Air Force base.
The gathering, which has been referred to as a "pre-dawn celebration," reportedly took place around 3:00 a.m. PT. People in costumes, UFO and alien enthusiasts, and tourists responded to the call, and arrived at a gate that was being guarded by armed members of law enforcement. The mood seemed joyful and positive.
