My son had seen my Pinewood trophies and began to talk about his expectation to build a fast penguin car so he could fill a trophy case of his own. We talked about realistic expectations. I suggested for the first year, we build a car that would make it down the track without falling apart. He wanted more. He could see the penguin, too, and if we could see a black-and-white penguin in a block of brown wood, then speed could be obtained, too. Then I remembered Dad.
