I used to work (1990’s) just down the street from Ford’s River Rouge plant. Sometimes on my lunch break I’d drive down just to poke around. Pretty cool . . . you could see the docks where the ships unloaded their iron ore, etc. By the 90’s I think the terminal already belonged to another steel company. So the complex was in separate pieces.
It hasn’t worked that way for a long, long time. Though I do have a friend that does high end contracting. Clients regularly send him to the marble quarries in Italy to inspect the marble for their bathrooms and entranceways while it’s still in the ground.
