I had a few minutes of boredom here at work and was sifting through patents of people's deer hunting ideas and came across a tail-wagger. The tail-wagger was later picked up by Come alive decoy company. I was just wondering if any of you had used one and if it worked. If your like me and had never seen such, check out tail-wagger.com. They make one for predators that looks believable enough but I ain't to sure about the deer butt version.
