A friend of mine and wife went to see Area 51 on vacation to Vegas. He got too close near the outer perimeter and a car showed up with 2 armed guards. The must have already looked him up as they knew his name, address, where he worked and that they were on vacation. They said something like he'd better go back to Vegas and enjoy his vacation. The car followed them all the way back to Vegas to make sure they were leaving.
They don't play around out there so I wouldn't test them. Hell, about 30 people working their got seriously sick from something they burned on site. They hired a lawyer to sue and were stonewalled in court.
Sounds like another millennial "Fillintheblank challenge".
