There has to be better options available. The opening pages tell about the mail carrier getting stung by icy wind and not letting the cold weather stop him. I’m sure the mail carriers in Florida rarely face such an issue. Later it tells about how the mail carriers sort the mail at the post office before loading it into trucks and their mailbags. Yet I am pretty sure that large urban post offices have different people doing the sorting than the ones making the deliveries, and possibly even different folks loading the trucks. I don’t believe in over-simplifying when writing for small children. Simple, straightforward text is one thing, but simplifying to the point of distorting the facts is not fair to young readers.
