These three little Michigan communities barely exist anymore, and rarely show up on maps. The first one is CAMPBELL, in the U.P.’s Delta County. It was basically a station on the Chicago and Northwestern Railroad beginning in 1878. The nearest school was a couple of miles east and the closest post office was north in Defiance. All shopping and trading needed to be done in Defiance; the town had a blacksmith, general store, meat preservation building, sawmills, and a shoemaker. Campbell had none.
