We had a guy in our club that evidently had been watching to much outdoor channel and had most of the gimmicks they use. One those kinds that always sees big deer but never kills anything. One morning he had signed out the area next to my area. Turns out we were hunting about 200 yards apart on opposite sides of the creek. He couldn't see me and didn't know I was there. Just after good shooting light he started calling and did so every 15 minutes. He would do several can calls then blow a grunt call like playing a tuba. It was the most awful racket you have ever heard. This went on for over an hour and I, having give up on seeing a deer, couldn't take it anymore so after one of his calling sequences I grunted back at him a couple times. He went to can calling and blowing his grunt tube like a mad man. Every time he would get quiet I would grunt a couple times and this would set him off again. He finally gave up and left about 9:30 and I was able to hunt in piece and quiet.
