One day a Professional?

Nathan currently can start and drive our four wheeler. He has been doing this since he was two years old. He rides through the tree trails his Daddy made them. He is amazing. This picture is of him on his brother's dirt bike. Daddy is working on getting him to ride the dirt bike w/ training wheels. I am not sure i am ready for that. Nathan is such a big boy. He doesn't get that he is 3. All he knows is that he can do whatever his brother and sister can do.
