I was told this a few years ago as as far as i can tell it holds true. In the fall of the year the shad start gathering in schools and become the bass main meal. So i usually use lures that target from the top to about 5-10 foot down and have had great luck. Bass mainly are looking toward the surface for food. But not to say that they can not be caught on worms,jigs,etc. I just catch a lot more toward the surface than on the bottom. Good luck fall fishing everybody,jc
