Grampa used to sack up a half toe- sack with green black walnuts . Crush them with the tractor ,running over them multiple times . Drag them behind the boat in sloughs and the fish with scales would float to the top . He would dip as many as needed and rest would go back down in a few minutes . Every time we would go bass fishing and got no bite my older brother would say poppa done been here lets go somewhere else .
