Not sure about your deer population or the amount of people in your area hunting (mine is high and heavy) but I have found if you hunt the does, the bucks will follow.

But then again, 4.5 years olds are what we are finally getting to in my area, so there aren't that many around, (hopefully 2-3 from the sheds and deer I saw at the end of the late bow season, will be around this upcoming season) and with around 200 acres to hunt, there isn't alot of places you can go.
