 On occasion, we did find pictographs or petroglyphs, but we were really kind of wondering what these confounded fences were all about. And we ran into a lot of them over the years. And then we finally were threatened after going into one place six times. A man who had a Department of Defense ID badge confronted me about going into them. And he said, look, I know what you've been doing in there. I know where you've been. I know how many times you've been there.
