Be prepared!
The theme of this book (possibly unintentional) is 'mother nature doesn't care about anyone'. These stories show that even those who go into the woods with skill and proper equipment may not come out. Weather can deteriorate in minutes unleashing avalanches, floods, straight line winds, rainstorms, hurricanes, lightning, blizzards and more. The less skilled hiker without proper equipment should stick to well-marked trails.
I was impressed at the time, effort and expense that goes into searching for hikers who get lost.
