He loves working on stuff. I encourage it in both of the kids, my daughter is just not into getting filthy under a truck though. He works on all the cars around the house as well as lawn tractors, lawn mowers, his mini bike and all the RC stuff we have. He is my mechanic. I just have to give him some instructions and turn him loose. He also knows that I will rag him to the end of days if he does stuff in a not savory way. It has made him more detail oriented and less of a ham fist. I started him off early. These are all when he was just about 3. He turns 18 on Thursday.
