I am a SAR team member in NY State. Most wilderness SAR activity is handled quickly, within a few hours by NYSDEC Rangers. Thanks to increased cell phone service, large "campaign" level incients are relatively rare and less involving trained volunteeers. Apart from the ubiquitous "lower leg injury", when I receive ranger's reports, every week, there is almost alwayssome incident where failure to adequately plan for darkness, or time, no compass or knowledge how to read it or a map, or with inadequate clothing (especially footwear) is the common cause. "But my cell phone has a flashllight built in" is one that really gets me. Some of these are ripe for assessing a "dumb fee".
On the other hand, I was recently on two recovery searches. One for an Alzheimers patient who walked out of her home and was found in the woods deceased 3 days later with the help of a trail camera photo that she walked past. Just a week later a hunter was found where he sat on the ground next to a tree, suffering a fatal heart attack after dragging his just shot deer about 50 feet. Who gets charged for those incidents?
