The Soo serves as a microcosm of relations between America and Canada. From the War of 1812 to the furor over free trade, and now to the exciting cooperation in education and friendship festivals, the love-hate relationship between Canada and the U.S. has always been keenly felt by the twin city that straddles the St. Mary's River. The Border at Sault Ste. Marie reviews the military activity, business, cultural, and religious developments, as well as politics on both sides of the border. It shows how the two Saults shared each other's national history and had a vibrant life of their own.
