Right now we go through ebbs and flows, the peaks and valleys, where we go from good performance to bad performance. One of the real tests, as we go into winter, for instance, in the grain industry is that the snow will fall, the trains will start to bog down, and there will be derailments. Come spring, we'll find landslides and all sorts of challenges for the railways. On the west coast we'll have wind; we'll have rain that will inhibit loading and will delay ships.
The one thing that we can't always measure or monitor or understand is how all of those external things have an impact on our supply chain. How can you be prepared for it, and what's the right level of preparation? I think one of our biggest challenges is to make sure there's enough surge capacity within the system so we can recover from those events quickly. Historically, that has been our biggest downfall. When you have one domino fall, as Gordon said, the whole thing can crash in, and then we go for months and months where it just never recovers. I see that as one of our weak points. We've got to be really good at what we do, because we're not the low-cost provider; we are the quality provider in what we do.
I think that's it, in general, and then you can dive into the other....
