I gotta disagree with people who say the size of tree don't matter. I never did see this particular buck that was making rubs in our woods but he first started out hitting 3" tree's and from there on the next year he moved over to a tree that was 4" and then the next year he rubbed a tree 10' from the other rubs that was a good 6"! He raked this tree very well, little guy's don't and can't do this! He rubbed about an inch or so in the tree, that takes strength and nice antlers to do so!
