Are UFOs real? Historical markers say yes
The nation has at least 15 markers telling the story of space aliens visiting Earth. UFO enthusiasts say they like to plan road trips from one marker to the next. There’s no way to really know what happened that night in 1973, when the men waded headfirst into one of humanity’s greatest mysteries: Are we alone? But the marker is now one of at least 15 that say, without hesitation, that aliens have come to visit Earth.
