Hrmmm...that's a tough one! I remember standing on the stump of my grandparents lawn at 4:15 every afternoon to watch the train run through town. Being young and living in a small town, the fast and loud locomotive flying through town was awesome to me. I'd go out every afternoon. I think they knew that I'd be a curious child then. It's also why they decided I needed to live somewhere else than the small town that had a train to keep my attention. :)
