While I'm sure all the other guides for this company are fabulous, we were very fortunate to have Don Moss, a gentle old soul who was passionate about Navajo culture and, especially, educating others about it. We could have listened all day to his fascinating explanations about the meaning of Navajo words and symbols, the history of the area and examples of Navajo code talking - a vehicle is a "chida". All this while still visiting all the photo op locations. Very memorable excursion. Highly recommend.
