I'm working an angle to get back for the ML season. From what I've read over the past few years is that Ohio deer start dropping their antlers at the end of December. Is that your observations also?
One of the worse feelings in the world has to be killing a huge deer and find 2 huge red dots on its head when you walk up on it! Solution: don't shoot at a big bodied deer in Jan or near end of season. I'm with Lundy, the neck size and over all body size is a no brainer when trying to distinguish the difference between the two.
I know bucks drop earlier (saw 2 Sat of gun week missing 1 side) but I see several every year in NE OH carrying both sides into March.
