For me there's a lot more to it than being in a tree or on the ground. To even think about a longer shot on an animal everything would have to be right for me--even a relaxed animal could take a few steps in the time it takes an arrow to cover 40 yds.
The way I look at it is bowhunting is about how close you can get. Target archery is for seeing how far back you can get and still hit the target.
