Personally, I would talk to your boy! I am very cautious who I hunt with. If I have ANY doubts of someones ability to hunt safe. Lack of experience etc.. I don't hunt with them. Atleast not right away. And deffinately not on opening day. Not to mention your buddy should have consulted you first. However, maybe it could be good for you. The more people whom you are hunting buddies with, the more likely you will be able to potentially hunt somewhere you have never had the oppotunity before. There has to be a plus for everything right?
