Do you know the way to Treviso?

On the way home from Venice to Treviso airport Grandma started to panic. It got so bad that when they got to Preganzol station they got off the train and called Craig to find out if they had gone too far. It turned out that they were a short distance away from Treviso and that it would have been the next stop on the line. They had to wait for the next train.
