I spent a few nights in the canyon and it was fantastic. I saw not a soul until one evening I was gathering wood for a fire and out of nowhere an old Indian rode up to me. He had long hair, wore a vest and a hat and had a mule loaded down with supplies on it. He said he was tracking me and I asked him where he was headed. In was all he said. I asked him his name and he said Eddie. I think he was squatting in the wilderness. Who know who long he had lived out there. The Gila is certainly vast enough that someone can go unnoticed indefinately.
