I went out deer hunting the other day, just to kill a Saturday & was walking to my stand. I heard some hens cackling & cutting up down in a holler West of where I was walking & decided to try something. I sat down, threw my orange vest & cap in the bushes, & proceeded to "yelp" to the hens with nothing but my my voice. Twenty minutes later, I had a hen at 12 steps. I hope I can do this to a gobbler come next Spring.
Man, I have seen Preston Pittman do some amazing gobbling with nothing but his own vocal cords. Unreal.
