It's a process that will occur over a number of years. And it's a process, first of all, because in terms of demand for natural gas, it will take time for people to make the capital equipment changes that they need to make in order to be able to consume natural gas in trucks and trains and even in the oil patch. And likewise, for supply of natural gas, my guess is that there is still some small amount of drilling that's going on for dry gas. There are a lot of reasons for that, such as people trying to hold property by production and the like. But over time, if gas prices stay down here, my guess is that a lot of that gas -- a lot of that drilling will stop. We've seen, for example, over the past few weeks a number of producers in the Haynesville say that they are going -- they're laying down their rigs, and they're not going to start to drill for dry gas there again until prices get to somewhere between $4 and $4.50 per Mcf. The Haynesville, going back a year or 2, was one of the most prolific and the most profitable areas to produce natural gas. So we are seeing, in terms of producer plans to drill for dry gas, that they are no longer drilling or they're planning not to drill, and they're going to wait a good long time until prices get back to reasonable levels so they can earn a rate of return on their investment. Now that's different in drilling for wet gas. With wet gas, not only do you get natural gas, dry natural gas, but you also get natural gas liquids. And natural gas liquids, to a large extent, are priced off of oil. So oftentimes, people can drill for wet gas, which can represent 30% or 40% of the BTUs produced, but since the wet gas, propane -- since the wet gas constituents, the liquids, propane, butane, isobutane, natural gasoline and a few others, since those are priced off of oil, then in essence, the producer doesn't really care so much about the price of natural gas because the price of the liquids so dramatically outweighs the value of the natural gas that's being produced.
