I have a new favorite TV show . . . Man vs. Wild on the Discovery Channel. For the uninitiated, Man vs. Wild features Bear Grihl, a veteran of the British Army Special Forces in a variety of desparate situations . . . abandoned in the jungle, adrift at sea, lost in the Everglades, and so forth. His goal: find his way to safety and civilization. All he has with him are a knife, flint, and a water bottle. Along the way, Bear (great name!) demonstrates various survival skills and techniques.
If you haven't watched Man vs. Wild, do so. It is great TV.
