I have bow hunted from a tree stand for 25 years and taken some shots I am not proud of in my early years but not a 36 yard spine shot! With the wind this sounds like a troll more than a legit post. More ammo for the antis! Hope you find him. Look for sign not just blood. Leaves turned and so forth. In the future please, for your sake and all hunters, make better decisions on shot selection. We owe it to the anamal.
