On clear nights with full moon, put out a few jug lines in the open lakes. Put the hooks about 6 inches from the surface and bait'em up with tin foil. Trust me.......you won't catch any small ones this way. Only monsters. So if you don't catch anything, then they simply aren't there. Try another spot. When you find a spot that consistantly produces, put out the trot lines and make plenty of room in your freezer.
