Prime example why I'm glad I got to hunt with Roger Norris this year. We both tagged out on a couple beautiful mule deer a week ago today. Both were killed in the evening and the temps were only getting into the low 50's. I was content leaving them hang till morning then taking care of business, but Roger's wisdom convinced me of the proper thing to do. We started at 9 PM skinning and quartering the deer, and when cutting the hind quarters off 5 (or so) hrs after the kill, they were still warm to the touch. Got done with field butchering both deer at 11:30. Best thing we could have done was exactly what we did.
We layered the meat in between layers of ice in 2 different coolers. The looks on the "Hunters'" faces when I show up to the bar to get a bunch of bags of ice was priceless. Here they were all decked out in camo, driking, smoking and watching the Broncos playing football and I had the nerve to ask for bagged ice from the bar maid. She asked what are they for, to which I replied "we have 2 hanging in camp and we need to cool them down". Everyone just looked at me, and I took the opporrunity to also say "Got both of them with a Longbow too".
We got the coolers full, opened the drain plug so the meat wouldn't be sitting in water (I had a hitch haul to hold the coolers) stopped 1/2 way home on a 26 hour drive to add ice. Even made it thru S. Dakota and there 100+° weather with no problems.
Dropped the meat at the processor on Saturday evening still packed in ice and picked it up Sunday evening. It is the best venison I have ever ate. Even had the heart packed in there with it, and after sitting in the fridge till last night, I cooked it up for desert for my boys and I. With generic Seasoning salt and black pepper sprinkled on top of the pieces, it was fantastic.
The Key like everyone has said is get the hide off and meat cooled down.
