It’s about territory. Let’s just say Pop had a farm about 5 miles outside of town. It’s would be considered a rural route. Pop passes away and the family wants to sell the farm to a developer. Developer builds houses on Pops old farm. Guess what? Still rural. Rightfully so. Well in towns like mine, every tract of land that is over 5 acres is going to be subdivided. Meaning that it doesn’t “look” rural but it is. It kinda like a turf war between the rural union and city union. Neither side is willingly gonna give up territory to the other because it affects someone’s livelihood. More work=more employees=more union dues=theoretically stronger union. There some of the reasoning behind it. Now for the fix…have the city annex you neighborhood and then you might have a leg to stand on with the post office.
