Herds of wild pigs – dubbed “super pigs” for their size, intelligence, and hardiness –  have been spotted within 10 miles of the US border and North Dakota. Invasive pigs have had a foothold in Canada since the 1980s, when farmers began breeding domestic pigs with wild boars imported from Europe. But there wasn’t much of a demand for the new breed of Canadian bacon and the Frankenpigs were turned loose.
