“Mail in a Pail”? Michigan is the only place in the world with a floating post office. Michigan has many huge rivers and lakes which are used by big ships called freighters to transport things. These ships cannot stop in the middle of a river so people can get off and mail a letter or go shopping. So in 1874 J.W. Westcott started a US mail delivery service by rowing a boat out to the freighter, who would toss a bucket or pail over the side for its mail. The current boat, J.W. Westcott II even has its own zip code – 48222. In addition to the mail, deliveries have included books, candy and even the occasional pizza!
