When I was 5, we lived in the country for a year. There was a rail line that passed right near the bottom of our vegetable garden; I could see the trains from my bedroom window. I would stay up all night watching them. At the end of the year we moved to Winnipeg, and I just assumed that there would be a train through our backyard there, too. I was crushed when there wasn't.
