---And what's up with all the barns in random locations with no farmhouses? Some of those poor farmers evidently have a long drive from the town. Not only that there's no roads so they must have to ride horses (or sheep).
There's several variations in farming in different countries. Here in Finland farms were/are in random locations, the farmer living somewhere in the middle of his fields far from towns and even far from each other. In Germany, most people including farmers live(d) in villages surrounded by quite large field areas. There's pros and cons in both systems. I agree, though, that the grain silos in the middle of nowhere look odd...
-My mom used to work as a henhouse consultant in the fifties and sixties, driving a moped all around this country. Been given instructions from the previous farm she had worked in, she drove away, looking for the byway to the next farm. After a while she came to some farm or village, asking for the road. It appeared that she had missed the byway. So, with new instructions she drove back, still not finding anything like a crossroad, not even a path at places matching the landmarks she was told about. Apparently the farmer walked through the woods when he had to deal with other people, skied in winter.
Considering AH being a WW2 game, American style modern highways would look odd, too. In the forties it wasn't uncommon not to have roads between villages and towns deep in the countryside, only paths and tracks. There still might be only one way from one little town to another, as I noticed a couple of years ago in Eastern France: Our trip took through a small town, much alike those in AH, but the road to the next one was closed for repairs. My navigator device couldn't find an alternative, suggesting only a forest path allowed only for the Natural Park service personnel...
