Tony, I THINK they are referring to that bone thing that's left once you take all the meat off???
Seriously, I also load the smoker, so there is always a good deal left over. I fridge what we'll eat in a week in plastic, with a little NC vinegary sauce in the bottom. Everything else goes in one pound portions in ziplock freezer bags that then go into the chest. I reheat stove top (or micro in a pinch) with a little more NC sauce for moisture. (Not much.) It holds up just fine. If I am storing for distribution, I store in 1 pound lots in styrofoam cups with plastic lids, which are then wrapped in plastic wrap before freezing.
