America’s Only Floating Post Office Delivers More than Mail to Detroit’s Ships

(via Atlas Obscura) The J.W. Westcott Company has served ships carrying cargo that pass through the Detroit River as history has unfolded around it. It’s been here since before Henry Ford test drove his first automobile in Detroit, present for the rise of Motown Records, throughout the 1967 race riots and when the city filed for bankruptcy after decades of economic and social turmoil. Eventually, the Westcott Company’s essential role on the Detroit River led them to become the only boat in the country with its own zip code: 48222.
