“…[A] word of caution: Do not jump into your automobile next June and rush out to the canyon country hoping to see some of that which I have attempted to evoke in these pages. In the first place you can’t see anything from a car; you’ve got to get out…and walk, better yet crawl, on hands and knees, over the sandstone and through the thornbush and cactus. When traces of blood begin to mark your trail you’ll see something, maybe.”
