 on the Colorado River, on some of the big reservoirs there, as well as the Colorado River through Grand Canyon. But the book's really about a lot more than that. You see, it starts off with Colleen's divorce at the age of 40 and how she used these journeys to navigate some of the rough patches of her life that followed and find her own way back to a good place in life. I think you're going to really enjoy this conversation. Again, it's an extended one covering two segments that we'll have with Colleen today.
