Why argue over this? Theres an easier way to explain it. Its called " shi+ Happens" .
It is also called I know I hit the deer really high and I never found him so it must be the mythical " hollow spot" !
kegei I have an important question about the " healed" deer killed later on, was the scar/wound above or below the spine?
I will beleive in the hollow space when someone can show me them slipping a broadhead below the spine all the way and not hit the spine arterty, the lung cavity or the lungs.
