Keaton who is now 12 was calling elk before he could say the word. Point to a picture and he would start calling. He has become a very useful tool. Keep working on that boy! Take him scouting and hunting, I did. I even carried him on my back until he was 4 and could walk the trails on his own. The thing I learned is to quit when my son had enough, now he can't get enough. And don't forget really good clothes. Expensive but worth every penny in the long run.
