While a good idea in theory, I wonder if there could be legal issues of being forced to pay for a rescue that you did not ask for. I wonder if there should be (or is) some sort of waiver form that says “Yes, I authorize rescue efforts” or “No, leave my dumb butt out there (with the appropriate release of liability legalese included)”.
