RE: deer carcus....?
At home on the farm, they get put in the bucket of the Deere and we haul them off to a hole we have dug for that purpose....
Locally, I butcher on the land that I kill them on, leave it in the woods...I do carry the deer a few hundred yards away from my stand area...Just find a good tree and use your climber to hang the deer on (make sure you strap it good to the tree)....Or, find you 2 trees about 4-5 feet apart and screw two eyebolts into the side, take a couple of rachet pulleys and pull the deer up to clean....
Just carry your cooler in the truck, throw the cuts in there and pick up ice on the way home...
The remains will be gone within a week...
