Imagine living someplace where you had to travel from room to room by ladder. If you can’t, then you are probably old and arthritic like me. Either that, or you’ve already tried it and not survived to share the experience.
This particular location is called Montezuma’s Castle, located just southeast of Sedona, Arizona. In it’s day (500 years ago or so) it was a thriving community of cliff dwelling Sinuagua Native Americans. In those days, there weren’t governmental agencies to outline building codes or enforce child endangerment laws. They seemed to do just fine.
What finally did in this society? Well, the best guess is rapid population growth followed by the gradual disappearance of the local water supply. They tried to blame it on global warming, of course.
