My vast metropolis has less than 100 people living in it. We're naturally part of a larger school district.
There used to be a lot more even smaller "towns" around here but by about 100 years ago they were already disappearing as business came to these bigger little towns.
Here is video on Youtube of our small town high school football team in rural north eastern California team playing a team from San Diego. The San Diego team made a 400 mile trip north to play, only to lose the game.
