After the shot is fired thats when the work starts, study up on how to skin and bone an elk thats laying on the ground, have at least 2 good knives, a stone and steel, and some rope, take plenty of game bags. I have found it to take 4 to 6 deer sized bags to bag up all of the boned out meat, also take lots of black pepper, if the bugs are out cover the meat with a heavy coat of pepper to keep them off and when you get it home, most of it will wash off. Don't scrimp on a pack frame get one with good pads and pack your load as high on your back as you can, it will be easier to control. Don't forget it is fairly easy to lift 100 lbs in a pack but carying it for several miles is something else, don't over load your self
Good Luck
