Canoedogs clearly has done this before, based on his comments above and other posts of his I recall reading. Obviously, his chances of doing what he described are both pretty darn good and a lot better than mine. Still, I'd take a PLB.

A lot of things can go wrong; a twisted or broken ankle, simply getting ill, or otherwise somehow getting immobilized. The PLB is insurance. We don't think most things for which we are insured will ever happen, but we are insured all the same.
