Ah, the beauty of a sport that makes us ponder these questions! I'm getting to the point that I can go out and watch others catch fish and enjoy that in itself. But just let a fish refuse a fly and it stirs something primal in me to get it to strike.... Then all the accumulated information, experience and theory of a lifetime of angling comes into play. (Maybe it's partly the image in my mind of being outwitted by a creature with a brain the size of a pea....) Maybe it doesn't matter to the fish, but what's important is - it matters to me.... Thanks for the post, Jim
