In Norway they used to put hay on metal wires, tied to high poles, making a fence of hay that dries quickly in the sun. Then the dry hay was stored indoors in hay silos for the winter, usually with formic acid to keep it from rotting. I suspect this was the norm through-out Scandinavia. You only rarely see these long lines of hay today. Instead hay-bales rolled in white plastic are now the norm, sometimes humorously called tractor eggs... Anyway, whenever I see a farm doing it the old way, I make sure to take a photo. I had a lot of fun playing around in the hay when I was a kid, running under those posts and climbing them, and doing all kinds of shenanigans.
