Once again, the problem seems to be one of SEND (Satellite Emergency Notification Devices) units providing a back-stop for folks going on a hike ill-prepared. Forget the basics; #1 on your 10 Essentials list is a SEND unit and #2 is spare batteries. You donít need boots, jackets, water or food; just start walking and when you find yourself cold, wet and hungry, or simply lost, just press the little red get-out-of-jail-free button. Ainít technology great.
