Oats and beans and barley grow

You don't have to travel very far out of Chicago into Illinois before the horizon becomes littered with grain silos:

It took me a while to work out why these looked so odd to me, but I think I've got it now. Firstly, farms here don't have any hedgerows, so the whole scenery looks a bit different. Secondly, having spent my formative years in the garden of England that is the county of Kent, I have oast houses stuck in my brain as the primary method of drying/storing grains.

And aren't they pretty?
