Funny (ok, not so funny...) story from MSNBC, which I don't normally read.
About the use of plb's to call for help. Appears many rescue groups think that people are trying to do more than they are capable of because they have plb's as a backup.

The Grand Canyon's Royal Arch loop, the National Park Service warns, "has a million ways to get into serious trouble" for those lacking skill and good judgment. One evening the fathers-and-sons team activated their beacon when they ran out of water.
Rescuers, who did not know the nature of the call, could not launch the helicopter until morning. When the rescuers arrived, the group had found a stream and declined help.
That night, they activated the emergency beacon again. This time the Arizona Department of Public Safety helicopter, which has night vision capabilities, launched into emergency mode.
When rescuers found them, the hikers were worried they might become dehydrated because the water they found tasted salty. They declined an evacuation, and the crew left water.
The following morning the group called for help again. This time, according to a park service report, rescuers took them out and cited the leader for "creating a hazardous condition" for the rescue teams.
