I had a one time hunt with a war veteran years ago, figured he had some weapons and tactics experience anyway, and had a young son chomping at the bit. I figured what the heck. All day long we let them block draws, hunting pheasants, walk in on the points when in quail areas. No matter how many explanations we offered, these two would post somewhere other than planned, hiding behind a tree or other cover, so that the drivers had no idea where they were, and wouldn't dare shoot. On quail, they would refuse to flush, standing back and encourage the dogs forward, thankfully the dogs were broke and knew better, but left me to flush, and risk being sluiced by the newbies. Shot at a quail covey literally in the yard of a farmer friend, on the ground, running, both quail and men, through the kids playground equipment, while I was inside visiting, and humiliated. All these were mistakes of being green, but there was either no learning curve, or limited learning curve. It was to much for me, I now require a session of dog training/target shooting, and casual discussion of the way things are done, prior to an invite to a live hunting day.
