While reading the article, I was also wondering if this particular type of haystack is really uniquely Romanian. Although nowadays you have a much greater chance of seeing these in Romania, where there is a lot of hilly/montainous terrain which is not suited to the mechanical contraptions that spit out hay rolls (plus arguably in Romania there are more poor farmers who can't afford mechanical contraptions for their hay, or have plots so small that using a mechanical contraption is not worth it).
