Sometimes here in West it is pretty warm during the early archey season. You need to prepare for getting you animal skinned out and cooled down as soon as possible. Getting the hide off quickly is really important. Another thing I have done in the past is carry a can of black pepper in my pack. Once your animal is gutted sprinkle it liberally in the open cavity to keep the flies off of it until you can get it out of the woods. Then, get some ice on it or get it to adeep freeze or cooler as soon as possible.
