RE: buck growl
My first year bowhunting, I spined a yearling buck, and he crawled down into a creek, where I missed him with my last two arrows. So, I had to climb down there and cut his throat with my knife. Let me tell you, an angry buck can make quite an array of interesting and aggressive noises, none of which sounded muchlike a bleat or a grunt call.
That's not to say that bucks run around "growling" in the woods. I'm just saying that they DO possess the ability to make several types of vocalizations. Even with that said, I won't be buying a buck growling call anytime soon. If my daypack gets any bigger, I'm gonna need a wheel barrow just to haul it to the stand.
