Book excerpt: A high-altitude alligator farm. A UFO watchtower. A monument to a headless chicken. While other travel guides tell you about tackling Pike's Peak, skiing the back bowls, or rafting down the Arkansas River, this quirky regional resource offers unusual travel destinations and little-known historical tidbits. Imagine regaling coworkers with unique Rocky Mountain adventures, like spending an evening at a drive-in movie . . . in a queen-sized bed, or visiting a vapor cave clad only in a towel. How about seeing a two-headed dragon made of car parts, or watching cliff divers while eating Mexican food?
