I have packed far more elk out on my back than I have ever seen whole. Given the large number I have been involved with a few are always up hill, close to the road, on a skid road or decommissioned road, but 90+%, are either "way" down or "way" up, with no "way" (pun intended), to move them other in lots of pieces. We have used chain saw winches, ropes, pulleys, cables, gear driven winches, ATV's, but I will say however that in my lifetime I have spent far more time hunting them , than packing them out !!! I also hunt a lot by myself and most other options don't work with one person.
