My brother showed up last year with the "Buck Bomb" (couldn't believe it). Said his buddy used it and had some story of maddness.
I used mine on day 2. It was a bomb allright. Another guy swears by the code blue and yet another drags pure vanilla though the woods.

I don't use anything anymore and just find where they are and am prepared to move if need be. Scent, sound and site free for me is my goal. Just let them think it's just another beautiful day in the neighborhood.

Get to know the animals and read the signs Is another approach. If the place is tore up the animal that did it is aggresive and will respond to like aggression. Know a guy who drove a deer out of it's mind in a rage and came with in a tree trunks distance to him and a boy he had with him. His dad watch from a distance the whole show. The boy paniced as you can imagine.
