The truth is tough but it's the truth nonetheless. If you're not getting busted then you're not in a good spot and not close enough to kill deer with a bow. Bow hunting is tough. It's an awesome feeling when you're able to get deer within range and they never know you're there, but that's not how it usually happens.
I hunt mature bucks with a bow. Rarely do I bow hunt for does. Pretty much every deer I see gets to pass right on by. I don't even grab my bow unless I see a rack frame that could be large enough to be the buck I'm after, or equivalent. Only two out of my six sits so far this season have I had deer within bow range & none of them snorted at me or caught my scent, and I've had numerous deer within range every sit. What usually happens is they come by and then catch me on the downwind side or they catch my ground scent from my walk in. It's almost always a deer I could have easily shot. But that's an accepted risk I take. It's a numbers game. I have to be on top of the deer for a bow shot, and when I have half a dozen deer filtering through the woods all around me, chances are good one will peg me. Every deer in that group will run off snorting, taking with them all of the deer in the immediate periphery. And that's ok. Eventually I'll catch big boy by himself and I'll finally be able to punch a tag. I bet I get snorted at 1000 times for every buck tag I punch.
