Haystacks!

Really... Kuriositas just answered a question I hadn't thought to ask though in retrospect it's a rather interesting problem - how DO you construct a haystack to keep all of the hay therein in good condition throughout the winter, rain, snow and all, all while removing bits from it every day, so that you can feed your livestock through said winter from it? This without so much as a roof over the thing. Here's how the Romanians have traditionally done it, and it's very well engineered. Looks interesting, too. Click on the photo for the article.
