In Carolyn's video, there is a miniature railroad rolling through a backyard. There are also small buildings made to scale that can be seen around the tracks and tunnel. It's a work of love.
Back to skiing, Sarah's video is actually a resume tape for a 9-year-old!
And finally, Carolyn ends the segment with a clip of a different kind of backyard railroad. This one is hand powered, and you can actually sit on it.
