I visited the UFO Watchtower near Saguache County when I went to Colorado a few months ago (you can find my post about it here: http://paranormalcrystal.blogspot.com/2015/05/visiting-ufo-watchtower.html), and when I was trying not to buy out the entire gift shop, I picked up That Crazy Lady Down the Road by Judy Messoline, who created and runs the Tower.
The UFO Watchtower overlooks the San Luis Valley, which is known as a UFO hot spot, and the first sighting at the watchtower occurred in June 2000. Judy was born in Colorado, grew up in Wheat Ridge, and moved to the San Luis Valley to raise cattle on 320 acres of land. Soon after moving there, many of the people Judy met told her about their encounters with UFOs (and she learned that cattle mutilations weren't uncommon in the Valley); she began joking about the area needing a UFO Watchtower and made it a reality in May 2000.
The book is full of information about the history of the UFO Watchtower, UFO encounters that visitors have told Judy about, and other fascinating stuff. Chapter 6 ("The Aliens") is fascinating, and Chapter 8, which is about people who have visited the Tower and told Judy about their experiences with alien abduction, is especially interesting. The book also includes more than 100 pages of transcriptions of Tower visitors describing UFO sightings they've had. That Crazy Lady Down the Road is a great read, and anyone interested in UFOs will probably enjoy it. You can order the book or find out more about the UFO Watchtower here:
