I usually leave an itinerary with a trusted individual with a clear understanding of when to call for help if I have not checked in. But I go to the woods to disconnect and for a change of pace from normal existence. If I pack a cell phone, it is turned off. It is nobody's business to track my whereabouts every ten minutes or so. If I were part of a SAR operation, this might be a very useful feature.

Just another guttural growl from the knuckle-dragging Neanderthal hunched at the back of the cave, shielding his eyes from the light of the campfire.
