When I used to hunt areas that were hot, I found elk had a lot of heat in the neck and front shoulders. By quartering them I could get them to cool faster and lessoned the chance of souring. Especially at the junction of the neck and shoulders.
I don't age my meat at all but in most cases once I get the quarters washed and wrapped, they are partially frozen by the next morning. If I have to leave them over night, I will have to leave them on the porch to thaw enough to skin. I usually skin the lower legs before leaving them because once they freeze they are difficult to work with.
I usually have to 'brush' them up to protect them overnight from birds. Twenty to thirty ravens can strip out rump roasts and tenderloins in a few hours.
I drug a bull within a mile of the house one time and left it on the side of the house while I went to the house to get the truck. In the 20 minutes it took me to return, a coyote ate about half the rump roasts.
