I’ve done it with a blacktail deer on Kodiak. If you think you have all the blood out, you don’t. My day pack was covered in blood. Looking back I’m not sure it was a good idea since mr. grizzly may have wanted it too. I wouldn’t have a quick way to drop it.
I saw this previously in one of Nathan Foster's books. ATV(s) cannot get to slopes where some of these animals are hunted. This is virtually the best and maybe the only way to pack out the meat. With the hunting season being year around there is not the number of hunters in the bush as there is during established hunting seasons in the U.S. and Canada.
