Personally, if you have permission from the land owner to retrieve a deer if it goes on his property you are golden. However, if you don't, I think I would get it soon. Unless you actually have a conversation with him, I think it sheds a bit of a negative light on hunter-landowner relations. I know if we find stands up right on the property line or notice somebody posted close and they have never talked to us about it, that upsets a lot of landowners. I just think we always need to be perfectly up front with people and it keeps everyone informed and relationships tend to build instead of deteriorate. Its a common courtesy thing in my opinion Please don't interpret this that you did something wrong, its an ethics thing and the promotion of positive hunter images and relations that are more important in the long run.
