Occurred on September 27, 2016 / Area 51, Edwards Air Force Base, Nevada
Info from Licensor: "We are a father and son team of adventure travelers. This was part of a larger trip to be lead presenters on Area 51 in Yosemite. On our way home, we were going by Area 51. I have mapped out several hidden entrances and we were exploring this hidden entrance. We saw the truck going up the road ahead of us and we followed them up. They turned around and came back down the road. We have been there many times and we were probably recognized and they turned around and came after us. As we stopped on the public land side of the boundary, they blocked the road."
