I've had the problem in the past with someone actually inviting thereself to come with me and my buddy. The kid isn't a veryknowledgableabout hunting. I made the mistake of going with him once and it wasn't good. He would do things that weren't nessecarily unsafe, but little things like not covering up well enough andtaking ridiculously far shots. You don't want to look like the bad guy, but when it's effecting your hunting it's hard not to say something. I didn't invite him back with us after that, and explained that I only had permission for my friend thatI always hunt with and myself to use that field, and I haven't had any probems since.
