Skeeter you don't think the 50 lbs of Ice might cool the deer down just a bit?
Last time i had to do this the hind quarters were at 38 degrees very quickly. I know this because I stuck a meat therm. in it just a couple hours after packing it in ice . The bankets keep the cold on the animal.How much air movement you get in a cooler or a frig?
I have said it before and will again getting the body temperature out is the most important factor after harvesting for us hunters
,Believe me packing a carcass in Ice will achieve this result. I spent 14 years as a chef kitchen manager so I do know a bit about proper care of meat.
Lay in a bath tub and cover your self with about 40 -50 lbs of ice and put couple balnkets over yourself and then get back to me.
