Only slightly less interesting in the same comment:

I used to hike a fair amount in the White Mountains in northern New England, and I made a point of reading the accident reports in Appalachia, the annual mountaineering journal of the Appalachian Mountain Club (see www.outdoors.org/publications/appalachia/index.cfm). Every fatality of the year is presented as a case study, and analyzed in terms of what went wrong. Reading those accident reports helped me to learn that people die in the mountains at all times of the year. Knowing how to get out of the woods before hypothermia sets in could in fact save one's life. Appalachia is a great learning tool.

This matter of case studies is intensely valuable.
