I always take an extra cooler we call "the freezer". I put 8 frozen gallon jugs of water and 60 lbs of cubes in two of the sections and leave the middle open or put in frozen food for use after the first five days. That cooler stays shut until meat needs to go in. We bone out our animals at the kill site and finish taking the cape off the head back at camp. The meat goes in the bottom of the cooler and the cape goes over the meat. We use waterproof bags designed for rafting to keep everything dry. You can keep an antelope or mule deer like this for a long time. We have had animals in the cooler for nine days with no problems. I prefer to leave "the freezer" closed and in the shade to keep it as cold as possible. On the trip home, I stop at the first opportunity, drain the water and fill with more cubes. Works great with temperatures in the 90's in NV and AZ. Caping an animal is really pretty easy. I bought a scalpel from Van Dykes and bring 6 blades per animal to be caped. I let the taxidermist turn the ears but I get the skin off the bone. I always go deep around the eyes, better to have too much than too little. I cut the gums where the flesh meets the jawbone to make sure I leave enough in the mouth. I've used two taxidermists on animals I've caped and they were both happy with the job I did and happy they didn't need to work on a stinky head. Make sure all the meat and fat is off the hide, fold it so skin is on skin and roll it up. If temperatures are cool, you can salt the cape and forgo putting it in the cooler. Don't salt and cool, it's one or the other.
