We have a booth at the antique mall in Fargo and I was helping my wife load up a few things and she was going to sell a buck head. Not mounted, just bare bone skull with a 4x4 that looked like it might of been cleaned with bugs because it was nice and clean. Anyway I told her it is against the law without a tag and she said she bought it at a sale so she didn't believe me , I'm not so sure that I was right but its not worth the hassle if its against the law . I know this has been hashed out but I don't recall the verdict .
