Here in the east ( Dacks), if you walk in 4-5 miles from the nearest road or trail, you can be pretty much assured of hunting day after day and never seeing a another human track.
Carrying 40 pounds in is easy, even the 2-3 hours of sweat and pain coming out with the camp and boned out deer isn't all that bad.
Moose or elk? I would want some friends
Now this is more realistic in perspective. And what we Hunt here are LARGE Mule Deer and Elk. So even with a Mule Deer "completely boned" out we are still talking about 80 to 100 Lbs of Meat depending on how old it is plus your Gear.
I agree that a Whitetail or Antelope would not be too bad under these circumstances of course.
