Myself and others I have hunted with have used anywhere from Chicken guts, I would about puke when taking the top off the 55gal drum, it would actually make a sound like when you twist the top off a pop bottle. We have also used bakery goods donuts, bread, Cookie Doe, Choc marshmellows ect. to bottled scents. I am not a avid bear hunter so I do not know all the tricks to it. But thats why I turn to you folks thanks.
