Shooting rapids, like landing an airplane, is not learned by making mistakes."" On this subject, the author should be an expert. This is his lively, unpretentious account of an exciting and highly dangerous canoe trip down 780 miles of Colorado's Green River accompanied by a group of boys, mostly around 13 years old, and mostly new to the sport. Their spirit and courage is amazing. The author in command of his prose, as well as the situation, renders an excellent account of adventure, insects, camp chow, and life. Always fair in his evaluations of his own weaknesses and the boys strengths, he concludes they ""weren't always noble, but they were never ignoble."" Good reading.
