I hate to always be the bearer of bad news, but as I understand it because these were not sheds you need a tag of some kind on them, or you are in illegal possion of a trophy rack. If it scores over 150 the fines are major. Also the regulations say that it must be taged before it is moved in any way. I know that lots of people have picked these up in the past but you need to know that you risk a citation, a fine, and having the horns confiscated especially by putting pictures on the internet of the head without a tag. The DNR might issue a salvage tag but you have to contact them.
