What I want to say is that I had a great time world building with my son, and we each helped each other with our projects. It was AWESOME bouncing ideas off of a young mind full of engineering and ideas and possibility. I've gotten this far in this post before, but if I try to say anymore, my stupid machine blows up.
Tomorrow I might have more patience, but now it's all gone. So let's just say, you might find inspiration closer than you think.
