There are a number of reasons actually.In my area it is quite difficult to gain permission to hunt private land and the pieces that you can gain access on are not very big,so in most instances you cannot hunt a deers entire daily pattern.I am in the catskills in NY and we have a tremendous amount of public land.The deer densities are not great but there is plenty of room to roam.The big woods is more conducive to rifle hunting in my opinion but that's where the biggest bucks in our area get killed.
