My temps here in N. Miss really don't cause much problem, but. I have 2 grunt tuhes and don't use either. I found that I can vocalize much better than either tube. I called in a 6 point (in velvet) from 400 yds. to within 15 feet of the wife and I. He stood there for 2-3 minutes studying us and finally walked on past us and returned to where he was before I called. I also used a deep grunt on a small 4 pt. that froze him in his tracks. Thinking that a big buck was in the area, he turned and returned to the thicket he had come out of.
I have retired my calls until I lose my voice ability.
