my buddy went to ohio last month and bow killed a deer at last light. He went back the next morning and recovered it. the meat was gangrous when he field dressed it. the meat had spoiled over night. I make every effort not to leave it overnight. even on a cold night it takes hours for the body temp to drop low enough to slow decomposition.
If you are thinking about doing it i would carry a block and tackle with me so you can hog dress it and hang it out of reach of the locals. then go back the next day and take it out.
