My parents are avid bowlers. They belong to a Friday night league. My oldest son who is now 6 took lessons and has his own ball now. My younger son, who is 3, plays with his plastic bowling ball and pins when we can’t make it to the lanes. He can already bowl on his own (with bumpers of course). Hubby and I enjoy it as well. So kids bowl free really works well for us. Bowling practically runs in our blood.
