If you have some time and do enough mindless searching you hopefully find something on the internet that may lead you to something else. Someone or some group posted this nice little map of where there once was one room schools and some cemetery sites. I knew of a couple of sites in the area simply by randomly stumbling across them. This area is about an hour from where I live and bears further investigation now that I know where some of this is located.
These days it is rural and not a lot out there. It should be fun.
