I use the harness that holds me in my tree stand for dragging. It has shoulder straps with one across the chest and the other around the waist. Then off the back is the long one (that attaches to the tree) with the slip hook. I loop that through the gambrelle slit between the tendon and the back legs (which I have to cut anyway to hang them)and drag them out tail first. they do not seem to catch on as much stuff as when I used to drag them out head first. OH.. and I always try to fall in the creek when I cross that.. it makes for a much more interesting hunt.
Once I get them to a skid trail then I go and get BIG RED...
the rest is easy after that.
