3D animation has made a big imprint on many kids, and the boy is no different. He was captivated by the movie "Cars," and the characters in it. He has a Lightning McQueen toy car, but also wanted Mac the truck to go with it. Why not make your own toy with Legos, I asked? He agreed to the idea, and helped me build the trailer that holds Lightning. I built the cab and the undercarriage, using mostly old pieces that my mom saved from when I was a kid. He loves it!
