Perhaps I could comment on your last question first, concerning border congestion. I think Canadians are as ingenious as anyone else in dealing with problems that way. One of the reasons, for instance, that we have the opportunity to transform Vancouver into a North American gateway from the Pacific, as a transit corridor into the rest of North America, has to do not only with our domestic infrastructure but with the fact that the port of Los Angeles and the other major ports on the U.S. west coast are too crowded. We have the capacity; people will choose to ship through us.
On the other hand, if the Canada-U.S. border gets clogged up, that starts to count against Vancouver as a gateway, and we have to deal with issues on the land border. The fact that we've seen congestion at some of the major land crossings, such as Windsor, has stimulated greater interest in water crossings, for instance, across the Great Lakes and short routes on inland waterways. If we fall down or get clogged up in one area, people are going to look for better solutions. That's a normal and ongoing process.
