They ia now a term "yuppie rescue". GPS, GPS tracking device, sat phones etc are giving people without the requisit experiance the boldness to try. In the rock climbing world it is the "5.11" gym climber who thinks he can climb the great walls of the Seirra or Rockies. In back packing it is the guy who tries to cross the grand canyon withlittle desert experiance. In a recent artical one man called for assistance three time on the third he was forced to evac. for indangerment of the SAR team. The prior 2, after being given water he refused evac. Thomas A.
