well, if he is draggin it away, sounds like it is his!!!!
i personally would give it to your buddy...but to each his own!!!finders keepers!!!public lands?private?just a deer, go find another....
on another note, there would be 2 holes if the arrow went through and through., but i think you are sayin two different arrows went through it.
no way to prove who's is who's..what can ya do w/o being in the wrong?!(laws eyes)
