Maybe Dane and I could talk about the natural gas side of things. You saw it in the prices. Natural gas, in particular, is basically driven by heating costs, and increasingly, as more and more people use air conditioning and you have gas-fired electricity, it's going to be driven by cooling costs. So it's very weather-dependent. Most models of natural gas prices can swing the market by as much as $4 or more, simply depending on whether you think you're going to have a cold winter or a particularly hot summer. So there's no question, in today's circumstances, that weather has that effect. The fear of unusual events—we hope, unusual events—like last year's hurricanes, can swing it further.
I'm not sure there's a lot you can do about that. You have to adapt to those circumstance, except—going back to Mr. Konow's point—to the extent that we can get more supply into the marketplace and that the underlying fundamentals are not as tight. In the case of natural gas, to the extent that we can get more storage—and investing in storage is a big issue for my industry—we can mitigate and dampen those effects. I don't think there's anything we can do to make it go away.
