I read this book in the late 1950’s or early 1960’s. It was in our school library. It was about a boy who was hired to carry the mail along the Florida coast before any development of the Florida coast took place. Along the way he saw many interesting sights and had various adventures. Finally he met a young girl and the two of them hid under an abandoned rowboat for protection in a hurricane. I don’t remember the title or the author. But I would sure like to be able to read that story again. It must have been written for older children or teens.
