A man travels across the Yukon with only a dog as his companion. He believes he has all the skill and preparations ready to survive it.
This always reminds me of Jack London's timeless short story "To Build a Fire":
Also timely, one of our power users at Referly just made a preparedness kit list for winter driving. I probably should have had some of this when driving alone in the Sierra Nevadas last month. http://refer.ly/winter_driving_preparedness_kit/c/789d5ae050...
Yet McCandless was essentially reckless rather than heroic. It's not that hard to die if you put yourself in an extreme situation, without preparing yourself or having any safeguards. It's a form of Russian roulette rather than "rejecting society"; though, I suppose, suicide is the ultimate form of rejecting society.
I see that he liked Jack London. So do I! However, I must wonder how thoroughly he read London's work, especially his Klondike gold rush stories, because very often in the stories the main character ends up dead, defeated by bad luck and an unsympathetic wilderness which is hostile to clueless men. I mean, did he read "To Build a Fire"?
Aside from what you mention, since basically you providing your own heat for yourself, you have to put or take off layers depending on physical activity. And so naturally this process involves too-hot and too-cold periods that are less than pleasant. Still, I survived to tell the tale.
I mean, we could all live like the hero of To Build A Fire, at least until we died.
