Ultimately it's driven by our buyers. Also, our buyers expect a product to show up on their doorstep at a certain time. Then we're given that timeframe and we try to meet it. The whole chain of action comes into play, and the railway is part of that chain of action. So we order the cars. We order the shipment. They tell us when they can get it there and then we try to meet that and coordinate the ships with that.
The problem is when the railways throw a hiccup into the system. Either they don't show up on time or don't pick up the cars on time. There's no recourse to the railways, but there's a recourse to everybody else in the system, and then the cost gets borne all the way back to the farmer. We've never had an opportunity to dictate to the railways. It's always been the railways dictating their schedule to us.
