If I'm close to home.....get it gutted and skinned and in the walk in cooler ASAP. If I'm away from the walk in cooler.....gutted and skinned ASAP and maybe deboned. Then it would go in a cooler with ice. If I can find shade, I would hang to firm up in the wind for as long as possible before going to the cooler. After the guts are out and the hide is off......the meat does real good in the shade for the most part.
If I was in the back country, I would cool in the wind, pack in dry bags (bone out) and submerge in a running creek. Most my bears are killed close to a cooler though.
