Spoke to a search and rescue tech one day, who mentioned that an EXPERIENCED hunter was late getting back from a sheep hunt in the mountains a couple years ago, and they were called in.
Found his truck at a trailhead after much searching, as he left only general info on where he was hunting, and they finally did find him. Apparently he was successful and had safely dropped off the first load of meat to his truck and was coming out with the second when he fell about 30 feet and got badly hurt. They determined that he survived for a day or so on the ledge, then finally expired. If he had a SPOT with him it could have made all the difference in this case, according to the search team! I've carried one in the packsack since then. Each to their own!
