The market forces that control the toll rates are, of course, the Detroit--Windsor tunnel, which is our competitor for automobile traffic. If our toll were to be out of line, we'd lose traffic to them, and vice-versa. Then, of course, with regard to commercial traffic, the Blue Water Bridge in Sarnia is our primary competitor for truck traffic, as well as the Ohio and Pennsylvania turnpikes for routes inside the United States to New York and New England.
