The thread linked below illustrates my concern regarding the financial consequences of a SAR effort that might be invoked by my Scouts:

Found, rescued and billed $15,000

My concern is the gray area between "We intentionally incurred unreasonable risks" and "We made a really dumb mistake and need help".

Given the possibility of a $15,000 charge for going off trail and then getting injured, I have directed my hiking crew to use the '911' feature only in a life-threatening situation. That leaves the responsibility of responding to a 'HELP' situation to the support team.
