All things change, I understand that, but some toys have lasted as long as the creations they are modeled after. My son is surrounded by an endless supply of gadgetry and electronic toys that people have bought him, but the standby toy is still the Train set. Maybe the train set fulfills the basic desire to create and build something that functions, or maybe trains are just cool machines that boys continue to love? It's fun to watch as I drink coffee, and sometimes I still have to get down there and help think up some new tracks. Now we just need to find some Lincoln Logs and we're set.
