RE: WHAT A TERRIBLE NIGHT-FROM A HIGH TO A LOW
Don't lose hope comndr45. I recall a similar post sometime in October, early November maybe, pics were posted after the harvest where the hunter seen the buck with his first arrow in almost the same spot.
Your assesment of the arrows path seems correct if you were above him at the time of the shot. The sparseness of blood you referred to leads me to believe what blood you did find would be consistant with skin and muscle leakage. Arteries and veins usually leave more volume and a more defined pattern.
Without knowing what the blood looked like as far as color and contents, it would be hard to say whether or not the lung was hit.
I hope you get him.
