Absolutely, and we also work closely with the Americans, and increasingly with the Mexicans, in terms of thinking about a kind of fortress America. If you take Seattle and you take Vancouver, for example, the Asian gypsy moth is a nasty little bug that wants to come from Asia. If Vancouver applies restrictions that are very expensive for ships, but Seattle doesn't, those ships could just go down to Seattle. Then the bugs would get into Seattle and then they'd come up north. It's very important that we work together on a kind of continent-wide basis.
