Today I noticed something interesting. If you use Google Maps to find directions, and you only give it a state instead of an actual address, it gives you directions to somewhere near the center of that state. So what would it look like if you drove there? What would you see, standing in the middle of each state?
Trees, most likely. The most common type of landscape seems to be forest interspersed with grassy areas (48% of states). Buildings and man-made structures are next (20%), followed by farm fields (16%). The least common landscapes are deserts and dry grasslands (14%).
If these pictures are typical of the whole country, the US is actually a rather sparsely-inhabited place. 20% of states show nothing manmade at all, apart from the road itself.
And apparently we grow a lot of corn. Cornfields showed up in five states (Delaware, Iowa, Illinois, Indiana, and Nebraska), which is more than any other crop, since no other crop was actually visible in any of the pictures. As far as I can tell, anyhow.
