Misnomer

A potato truck drove through a small town. It drove by many of the residents. The truck had no potatos inside. There was waste from an un named facility working with un named chemicals. The truck exhaled on these people. Five years later, a gross amount of them came down blind. Most could disern shapes, but not by the seventh year. 
That truck was only in town twenty minutes. The wide sightlessness was never traced to it. Never Ever.



Can you reconcile the image and the story?                        No?
Good.
