If you’d rather dress a deer than track it, make a promise to yourself that you will not release in these six situations.
I know there are some who will try to squeeze their arrow through a tight opening in some brush or other obstruction. However, there are simply too many things that can go wrong to take the risk. True, you may get through the obstacle between you and the deer. The problem is that nobody knows how your arrow will react if it happens to hit anything before it makes it to the intended target. You can hope that it would only result in a clean miss but there is also a very good chance you will strike the target with less than a lethal hit. This is where having a good grip on your limitations will help you make the right decision.
If there is plenty of space to allow a clean hit considering your skill level, then by all means, let your arrow fly. On the other hand, if you are not positive and cannot be sure beyond a shadow of a doubt -- Don't shoot!
