Slide 7 of 52: This one’s pretty out there – and, according to owner Judy Messoline and the many believers who make a pilgrimage to the site, they’re out there, too. This is the world’s first UFO Watchtower and people can book to camp by it in the San Luis Valley desert. There’s a UFO-themed garden and a small museum, too, and come nighttime there’s very little light pollution – perfect for spotting spaceships.
