I agree with the importance of getting it skinned and in a cooler quickly when the weather is warm but really don't think immediate skinning is necessary with cooler temps. I prefer to leave the hide on till I get them home and can skin them in a clean, controlled environment. As long as it is cool (preferably with a breeze) and has a good chance of getting into the 30s at night I let them stay unskinned, lying on their backs or hanging up. If warmer, I take blocks or bags of ice and stuff the chest cavity. Has worked well and I see know difference in flavor, but have to do a lot less trimming once they are home for processing.
