I kept one cow elk hide. Because it died 600 yards or so from the vehicle and I wanted one to go with the deer, moose, and bear hides already at home. With exception for carrying out the cape from a few bull elk, all others have been left in the field.
Kill, quarter, and pack out the meat from an elk a couple of times and you will view the value proposition of the effort and time packing out a hide differently.
Edit to add: I’m pretty much a solo backpack hunter, typically hunting with the bow in early to mid September. Once an elk is down getting the meat out is first priority. With temps sometimes in the upper 70’s - 90’s, packing out a hide doesn’t become top priority after 2-3 days of packing meat.
