RE: distance in treestand
Bull Hockey, you don't want to be aiming slightly high, you'll shoot high. In fact, the tendency is for people to shoot high because they don't bend at the waist and screw up their form. If anything you'd aim low before you aimed high. But the best is to practice practice practice at ALL distances from above and see for yourself. The horizontal distance will take care of the bear. When you range from in a tree with a range finder you should range straight out too to a tree, not to the base.
