The schools are most likely consolidated, meaning 2 or more communities are one school district. These kids will have gone to school with each other since kindergarten. Unless you inherit land or work for a local farmer, there really aren't many career opportunities. The only businesses in these little towns are the CoOp, where farmers sell their grain, probably a gas station and maybe a convenience store. Most shopping is done at the county seat or at the nearest larger city which could be as much as 100 miles away.
Doctors are also a distance.
Town was 30 miles from a hospital, and, since we lived in the country, we were about 45 miles from the hospital. Please dont think it's all bad, I loved growing up in such a small community. I spent countless hours with my grandparents. My grandmother delivered eggs every saturday morning to the ladies in town. We brought eggs, and visited for a few minutes at every house.
