I know it's a movie, but bare with me. In the John Rambo trailer J.R. is seen fishing with a bow and arrow with a line tied to the end of the arrow. Do people really fish like that? If so, I have made bow and arrows for sml. game, would this be an effective way to fish in a survival situation? I'm talking survival. The scenario is that I have nothing but a knife. Would this be easier than spear fishing?
