Next thing you know they are going to want to ban lawn darts... oh wait. When I first started playing dodgeball in elementary school we actually played it against a wall. It wasn't the two sides versus each other like you see in the movies and like they play in a gym. A row of kids stood against the wall outside the school and one or two people just threw the ball at them as hard as they could. Like you said, the sound of that kick ball hitting the wall or somebodys skin sticks with you for a long time. These days they use really soft balls I think. It is pretty pathetic! :P
