 It was a rather harebrained scheme, and a whole host of things just went off the rails from the very beginning. I think that's important what he just mentioned. That is honest, and when you read the book, that is all in there as well. So as you said, there's no single trail, and part of the trail includes the Colorado River, which you guys did paddle. Part of it includes hikes as high up as 3,000 feet above the river, from what I recall during our last conversation. Just give everyone a brief overview of the intensity of this physically and mentally, particularly when it comes to the terrain.
