I'm not sure exactly what the OP is talking about? Is he asking if we hold off on eating any part of an animal until it gets to town? The article he links doesn't show them eating raw meat but shows a guy cooking it on a pack stove.
I can't speak for anyone else but I always have some of the meat in the field. The heart and liver are always eaten for supper the same day the animal is taken unless it is taken right at dusk in which case it is eaten the next day. I've also been known to take the shanks and slow cook them in a dutch oven in the field since they simply become burger later. I've also been known to roast marrow bones in the fire in the field. Eating the meat is why I hunt and I'm not in the least bit squeamish about eating it after I shoot, clean and cut an animal.
