I like the fly rod theory. Those folk are funny, especially ones that cast big open loops; you know the kind of cast Bill Dance would make. If you look real close at fly fishers that cast that way you may notice a glazed look in their eye and a drooping jaw that results from a life time of mouth breathing. Yep, not much can be done to fix that. You could sock em in the nose, chew them a new butt hole or just give them a look of contemptuous disdain as you go home or move along to the next spot, it doesnt really matter what you do because they wont understand or change.
