Hi, I am trying to teach the 10 year old nextdoor to cast a flyrod. He seems to be a bright little kid, no visible signs of head trauma or injuries. Course, one more person that fell out of their crib one to many times isn't going to be noticable on this planet. Yet he doesn't seem to be able to grasp casting. He seems to have it stuck in his mind that he has to use his whole arm fully extended to cast. Should I tie his forearm down to his body? I gave him a stick with a piece of string on it to pratice with and it has helped but he quickly regresses. How about some ideas? Thanks
