Hello, This is my first year hunting with a bow and have a question regarding shooting from a tree stand. I sighted my bow in at 10,20,30, and 40 yards from the ground. If i am up in my tree stand do i have to aim differently if lets say a deer is at 20 yards. Do i put the 20 yard site on the kill zone as if i was on the ground, or do i have change the shot due to being in a stand. Many thanks in advance for the advise.
