At least two people were detained by local sheriff’s deputies at a gate to Area 51 after a crowd of about 75 gathered outside of the highly-classified military base in the early hours of Friday morning. The Associated Press reports that it wasn’t immediately clear whether a woman trying to duck under the gate and a man urinating nearby were arrested, but they were escorted away from the site by authorities. On Wednesday, people had already begun gathering in Rachel, Nev., the closest town to Area 51, in preparation for the alien-themed festival formerly known as Alienstock that is set to take place over the weekend.
