"Tired from a Tough Hike? Rescuers Fear Yuppie 911"

"Last month two men and their teenage sons tackled one of the world's most unforgiving summertime hikes: the Grand Canyon's parched and searing Royal Arch Loop. Along with bedrolls and freeze-dried food, the inexperienced backpackers carried a personal locator beacon -- just in case.

In the span of three days, the group pushed the panic button three times, mobilizing helicopters for dangerous, lifesaving rescues inside the steep canyon walls.

What was that emergency? The water they had found to quench their thirst 'tasted salty.'

If they had not been toting the device that works like Onstar for hikers, 'we would have never attempted this hike,' one of them said after the third rescue crew forced them to board their chopper. It's a growing problem facing the men and women who risk their lives when they believe others are in danger of losing theirs.

Technology has made calling for help instantaneous even in the most remote places. Because would-be adventurers can send GPS coordinates to rescuers with the touch of a button, some are exploring terrain they do not have the experience, knowledge or endurance to tackle."
