For many people, even the word "Detroit" brings to mind images of crime, cars and poverty. But no city can really be that black and white. The things you don't know about Detroit might just entertain you. Elovethiscity has a fun collection of 10 Detroit Facts You Should Know. For example, did you know the city hosts the only floating post office in America (shown above):
The J. W. Westcott II docks just South of The Ambassador Bridge along the western shore of the Detroit River. She is America’s only floating ZIP Code [48222]. Delivering over 100 years of “mail-by-the-pail”, the J.W. Westcott Company was originally formed in 1874 by Captain J.W. Westcott to inform passing vessels of changes in orders.
Today the 45-foot vessel’s duties include U.S. mail delivery; freight delivery, storage, forwarding; message service; passenger service to and from vessels and pilot boat services for the Port of Detroit. The Westcott also sells nautical charts, postcards, books, and has been known to deliver the occasional mid-river pizza.
