Like HCH said, we elk hunters leave carcasses behind all the time. You'd be hard pressed to walk national forest and find piles of bones a year later. We skin 'em where they fall, and debone them. We don't have to call anybody to report the kill. Simply attach your carcass tag to the hind 1/4 and leave proof of sex attached to the hind 1/4 and carry the meat out and process when ya get the chance!
Actually when I deer hunt my family farm in KS. we do drag our deer to a point where the ATV can reach them or the pick up, take them to the farm and hoist them up to skin! Throw the carcass out behind the shop and let the critters clean them up!
