RE: Big buck... what would you do?
Isn't it amazing how some people's views are different than others? Who in their right mind would take a buck that they did not kill and put it on their wall? Unless he's doing hiw own taxidermy, I would imagine he would have to tag it first...otherwise, the taxidermist can't help him. At least that's the law here in IL. If he's just going to put the rack on the wall, then what I just said doesn't matter.
If you and your buddy have strong convictions about it...and it means that much to you, then confront the guy. Take the civil approach first...then if that doesn't work, proceed accordingly.
Wish you and your buddy all the luck.
