I'm not sure, good question. We don't see alot of 0 degree weather in god's country here. But, I can tell you that when I've been hunting in 8-10 degree I didn't see a dang deer one! I think for such a drastic drop in temp, they don't move, cuz they are not acclimatized, compared to deer in Minnesota where that's normal. To answer your question I don't think it would be an issue. Not sure if scent would disepate or freeze when it's that freakin' cold. It seems that it would. Not really the dude to answer that quesiton....
