How do you aim if the terrain is not flat?

LittleRhody you want to aim low if your just using a fixed pin site. Practic at a target out of a tree and you will see. I saw a show on it once that said aim for the lower third of the deer. When your above the deer you can actually see more of the deer than you can actually shoot at. So if you see approx. 24inches you might only be physically able to hit a smaller portion of that.
