I've been known to go over the next ridge and the ridge after that and even the ridge after that if need be. If it ends up being 8 or 9 miles, well, the next day is usually followed by a little less ambition. lol. My hunting pack is capable of putting 100#+ load on it. If I were to get A BIG ONE that far in, I would debone it and try and get all the meat on one load out. If its cold out then its not a big deal. If its really hot I wont go that far back for several obvious reasons. The key is to be in great shape and it never hurts to be a little on the crazy side.
