It's hard to think that it stays that cold in South Carolina that long, but you are correct. It will not stink until it thaws. I don't use any bedding in my droppings board, just scrape it off when I need to so I'm not sure how that's going to work out. You may need to pay attention to it when it does thaw, it could be getting kind of thick. Or if that bedding absorbs all that moisture you might be OK for a while. Just kind of play it by ear.
