After the brain, and hand, definitely one of the first weapons. The Grouse in Montana are not the brightest either. They will fly up in a tree in front of you, and bob and weave their heads as you throw stones at them. The blue grouse, are worse. They will stop, and look at you, like did you just throw that at Me?
A good throwing stick will clean up on them. Of course, a couple of rocks will take em out also.
Good throwing, and good eating. At least you didn't go home being skunked!
