Johnny, I've hunted in some pretty cold conditions with my one-piece Bears- all forty years old plus or minus a year or two- and haven't had any problems. I've always worried more about extreme heat. Having said that, bows are like anything else in my experience in that they have a finite lifespan and any shot could be the last. Probably even more true with our "oldies". I'd hate to be the guy who told you not to sweat it right before one of your old favorites gave up the ghost. I will say we're having the same weather here in KY and I'll hunt with my '70 Super Kodiak this week. Maybe someone more confident giving advice will chime in pretty soon. For now I'd say, if you are really worried, don't do it. Nobody wants to hunt and worry at the same time. Good luck, stay warm. Grant
