Some days during the summer you can catch lots of hybrids in an area just casting something and retrieving just below the surface such as a chrome rattle trap, crank bait, swim bait, A-rig or slab. The fish may not surface ever or only a few times but they do suspend in the water column in the area. Those can be great days on the water. I have also seen people float corks with shad or minnows and wear the fish out as well. Good luck next time out.
