Nothing new to many. Take a 55 gallon drum with a lid and lock ring. Dump in 250 lbs of whole wheat and fill with water. Put on the lid and the ring and set behind the garage or other outbuilding in the sun for a couple of weeks and lookout. Stinks really bad and works up to about 35 foot of water. Draws in the channels and blues and works well with Sure Shot Punch bait.
