We do much the same with moose....gutless boning....packed into doubled polishing cloth bags [NAPA Auto Parts] and labeled {loin,neck etc].....we pack it away from the carcass and suspend it off the ground in shintangle until the next day when we finish packing the 15 40 pounders plus cape and rack.....we have had the gut pile hit by grizzly several times at night but seldom the meat.....luck?
