I'm a whitetail hunter from the southeast and I'm planning an elk hunt. I have a question about packing out meat. I've noticed when people sell their old backpacks on here, its common to see a note about how many or few bloodstains are on it. If you hang your elk meat/quarters in good breathable game bags in the shade, etc., is there any reason not to drop each game bag inside a plastic trash bag just before strapping it to your pack? Seems like it would be ok in the plastic bag if its only there during the actual time it takes to walk out and would keep from fouling up your pack. Will the plastic cause a problem with air flow or something? Or is there some other reason not to do this? Thanks all.
