I have just one point to add. We're talking about the rail system right now, but if we're going to be going after export markets, that will include the regulatory systems, the docking systems, the rail systems—a whole number of things. It's about value-added processing. There has to be an overall strategy to deal with this. This is one component. We know the bottleneck right now is rail, but we have to make sure that the system operates fluidly and that all the pieces fit together.
I think that ties in with some of the comments that were made about sharing data and information, because if we don't know what all of the partners are doing, it's pretty hard to design a system that works fluidly.
