Why dredge the bottom? Until the frost kills off the big grasshoppers and such, buzz a paddletail worm across the surface with enuf speed so that its tail spanks the surface. Want to go a little deeper? Twitch unweighted Zoom Flukes and Madtom's Sinkin' Salty Shads. Fall is also a good time for drifting Senkos and their ilk; I like baitfish colors.
