I've done something similar. I have a couple of neighbor boys that I introduced to bowhunting. I gave the older one my bow and bought myself a new one. I made sure he practiced a lot(he was 15 or so at the time) and tried to significantly shorten the "learning curve" for him and hung him a stand in a real nice spot and told him that I would leave this area for him to hunt. On his first morning out he killed a 7 pointer and later in the year he arrowed a doe. He was hooked. A year or two later his younger brother was feeling the archery bug biting him( he was 13 at the time,)so His brother gave him the bow that I had given him and we got him practicing and shooting well. He always absorbed everything that I tried to teach him and really seemed to have that "it"factor that makes some better than others at hunting. He arrowed a 130 inch 9 pointer in the third week of his season and has arrowed a few does since as well. It really feels good getting youngsters involved in our sport and seeing them be successful at it.
