I am a fan of Cody L. I have worked a lot in AZ and have a friend in Flagstafff that has known him for years. To work with my friend Chuck on the Navajo Res has been like a seminar in aboriginal thinking. The siting of early habitation sites is perfect with orientation to the sun for winter gain, and summer shade. We can all learn a lot by thinking this way. Native Americans have a knowledge base that is only slightly appreciated by most people.
