I hunt with my internal frame pack. It usually has a sleeping bag and bivy in it so I can spend the night. I compress it down so that it isn't too bulky, but I usually ditch the pack in the last few hundred yards of a stalk. I want to get the biggest load out first before my legs start feeling like jello. I might use a day pack if I had a buddy to go get the frame packs, but I like the challenge of getting an elk by myself. I bone the thing out putting the meat in 4 game bags and hang em in a tree. Bags go right in my pack, put anything I don't want soaked in blood on top of the meat.
