I don't think it has anything to do with age. As previously mentioned hunters have had run ins and disagreements with people of all ages. It comes down to the person and their own ability to be respectful and considerate. While you all have the same permission there has to be some respect between eachother and the areas you are hunting. It takes a lot of communication between all parties involved hunting the property. I have a property I deer hunt with others and we even share stands or allow others to hunt our stands when we are not going to be out. I also share a duck blind with a couple of guys and we have scheduled days that work best for everyone's schedule to have access to the blind. All parties involved need to work together no matter who had access first. Just need to sit down with the guy and get everyone on the same page.
