My father got into bow hunting when I was 8 yrs old. He decided to bring me into it at the same time. He decided to bring me to a local archery store/club and enrolled himself and I into their archery club. The club gathered once a week and had competitive shoots for the older guys and classes for the younger kids. I will tell you; by the age of 12 I could tell you anything about archery. Maybe not so much on bow hunting, but the art of archery. I harvested my first buck by myself with bow in hand that yr when I was 12.
What I was originally getting at before I headed down memory rd is. Make it a father son bonding experience. Shoot with him, join a club. He will be more apt to want to follow in your footsteps. Good Luck.
