RE: Would you shoot
I guess everyone has said it already, but at this point in my hunting life I will shoot pretty much any buck that I can get a clean shot on. I might pass on Spikes and definitely on button bucks.
As for does, I usually have the decision to shoot one or to let one pass before my butt even hits the stand. Late in the season anything becomes fair game (except the spikes and buttons).
Hunting is very personal to me and my decisions and criteria for shooting deer will vary greatly from more experienced hunters in different geography's.
