One of the trends that I talked about, which is the most important trend in the transportation business, is supply chain integration. One of the key factors in that has been containerization. If you look at what's happened with containerization, we've started to import a lot more product from different countries in containers. That has created empty containers, which has created a business opportunity for North Americans to export to other countries.
What we're seeing is that there is an opportunity in forest products, for example, to upgrade their products, put them in containers, and the cost factor of shipping those containers back to those countries is now there. I would agree with Joy when she said that it's not necessarily a bad thing when you start with a high number of imports. What that does is it creates the possibility of new trade on the way back. I agree we should add more value to our products on the way back, but having the trade patterns, the flows, and the agreements in place help that process.
