Excellent point about the inevitable administrative costs....

Plenty of people get into trouble without consciously assuming any kind of risk. Some years ago a couple was camped in the back country of Navajo National Monument at Keet Seel ruin in a designated and approved, etc.etc., NPS campsite.

During the day, there was spontaneous rock fall from the adjacent high cliff, killing one woman in the party, despite the presence of an experienced nurse (whom I knew personally) in the adjacent campsite. What was she doing wrong? Sometime stuff happens.

Sometimes we even rescued animals - stranded horses or on one occasion, a dog in a mine shaft. Our group chalked it up to training. There is a definite threshold in volunteer SAR. You need enough events to keep the membership active, but not overloaded and burned out. The pet owners were really grateful. For years the largest donation we ever received was from the grateful owners of the dog down the mine shaft
