During the early bow season one year I killed one late in the evening and had to work the next day, so I hung it in my shed, stuffed the body cavity full of ice bags, and wrapped a ski rope around it to keep the body cavity closed.
Fretted over it all day at work because it got up to about 80 degrees that day......But when I got home at 6:30pm only about a half gallon of ice had melted. A deers gut-hole is as good as a high dollar Yeti cooler when it comes to insulation. 👍
When I pulled the hide down the neck, head, and even the leg meat was cool as a cucumber.
