There are a few different ways to look at this. Certainly, on one aspect of the supply chain, we may see some change and balance over time between domestic and exports, because the biofuels market that you're talking about is largely focused on North America—Canada and the U.S.—so I would call that out.
Also with that, we anticipate seeing some change in movement and direction. That is not forsaking what we have in terms of that east-west movement that my colleagues were talking about earlier to ports, but also, given both the Canadian domestic market and the size of the U.S. market to the southwest, we will expect to see some increased north-south traffic, as well.
Dave and Steve might want to add to that.
