This is a fun ride. Probably some of the most enjoyable non-fiction prose on the market. John draws you into and through this wild network of adventures ratcheting between them, all the while weaving in bygone characters and events that give these adventures historical context. The only reason I left out the 5th star is because it really is a collection of stories and although they defer to a similar theme -- that adventure is dangerous and deadly to those willing to pursue it to it's purist conclusion, and possibly holds an allure worth celebrating -- it doesn't hold to a singular arch.

"I wheel into the grassy park below Aspen Mountain and start shooting photos of 156 ultra-runners attempting the Icebreaker Grand Traverse, a 42 mile run along the mountainous ridge stretching from Crested Butte to Aspen. It starts raining around noon and the park is a swirling mud hole. The runners are crushed. Several fall face down in the mud as they slosh across the finish. Some weep and laugh at the same time, as if their greatest joy might be running themselves to death."
