I just wanted to add that when we talked to the railway companies about the capacity that they're providing for the grain industry, they tend to look at past capacity and say they're doing well, and if you compare it to past capacity, they are. What we would like to see them do more of is compare the capacity that they're providing to the demand, and we are well short of that.
We're really looking at a paradigm shift. We're talking about increasing the amount of grain we're moving as the years go on. If we're talking about better agronomic practices and about higher-yielding varieties and about feeding the world, then we really are looking at a paradigm shift, and we really need to look at how we move this grain to the export terminal facilities and out of the country on a grander scale.
