Someone should tell them that the reason why there are so many vacant farms (East River) and ranches (West River), is because the Canadian and American farmers and ranchers have all emigrated to South America, for the same reasons they would be emigrating to South Dakota.

Someone should also tell them that South Dakota isn't exactly known as a dairy farming paradise...
