My hats off to Pappy:
This bird answered the keg from so far it was more cadence than sound that allowed for identification as a gobble. Came in fast and hard like a true two year old to the keg. I'm a wingbone man, got the tube from Pappy right before season this year, never used one before but with a little practice was producing some fine wind peircing or softer multi pitch yelps as desired, clucks were easy as well as an inferior gobble, I make wingbones, and have had good success with them, but after using the " killer keg " in the woods I can guarantee it will be in my vest on future turkey hunts.
