Believe it or not, even if you/he shoot a deer and it runs to property you don't have permission to hunt, you still cant go get it. If the land owner said NO you cant come on my property to get a dead deer, there is nothing you can do. Now he doesn't want to get caught with that deer, then that would be a problem for him if he doesn't have a tag. If he does he better tag it. NY DEC ( Department of Environmental and Conservation )told me this a couple of years ago. Just an FYI for you all.
