I found a fresh shed last year in middle Tn. the week after Christmas. Still had a spot of blood and some hair on it. I would not rule out shed. Also last year a co-worker took his nephew on the last weekend of season. The buck he shot had both sides but, as they drug him out one side popped off with ease he said. Anything is possible I guess but we really dont get the stressful weather conditions as the North or midwest does. That stress has alot to do with why they pop them off so early. Ill be honest, after last years odd find I was out hunting this morning and on my way out I took the deer trail out of the woods just for the reason of.....Maybe I will find a shed.....
