My father inlaw used the Renzo(sp) this year for the first time. The cardboard ones, his was the buck. He had it set up in one of the deer trails. This buck (bigger than the decoy) came trotting around the bend in the trail. I guess as soon as it saw it (pretty close) he just about went right to his knees, then popped up and hauled a$$. Being physically bigger, why would this buck take off as fast as it could? It was just about the right time to be seeing bucks challenge one another.
Anyways he hasn't used it since. I know he cut the antlers off of it and plans to use it as a doe next time. Thats about all I know about them!
