I have only had time to read to part 4 so far but a great article. And Thank You for bring back a great memory, back in the early 70's my Dad and my Uncle bought an electric race car set (the wide one), they said to my mom and aunt it was for me,( really) and Saturday afternoon when the races where on wide world of sports they would set it up in front of the TV and WE I mean I would would race those little cars around the track as the big race was on. Mom kept wondering how "I' kept spilling beer all over her green rug (you know the one thats really deep), it was about that time I would get picked up and put on the couch between my Dad and Uncle and we all had imaginary steering wheels and we were racing with the big guys on the TV.
