Great plans here!

I usually lash the deer to a 3-4 inch limb snug to the deer's underside.

Drape an orange vest high up, grab the head end of the pole and up and over the shoulder it goes.

Then dragging is no more than short hauls and long rests.

Had to do this in Luray VA a few times. Lots of ravines there. The first year I did that I came up on a still that had been trashed by some Revenuers years before. Interesting find.
