Yes, we're continuing to pursue rail solution. We just finished the rail facility at Sidney, which will bring crude out of the Bakken and allows us to take it into St. James. We're increasing our off-loading capacity at our St. James terminal from, I think, its 65,000 barrels a day to 130,000. And we're not the only ones that are pursuing the rail solution. So I would say that the market is adapting. It's much more expensive to move by rail than it is by pipeline. That said, if you have the wide differentials that we've been experiencing, there's enough economic incentive to overcome the transportation cost and the capital cost that it takes to build the facilities, so you can be able to do it with the wide spreads that we've had, and it's been effective. I mean, if you look at the inventories in Cushing, today, I think there are 32 million barrels roughly. And that's down from, call it, 42 million barrels in May. So over a 150-day period, it's come down 10 million barrels. Part of that is a function I think of -- as I mentioned to people, the easiest way to get crude out of Cushing is don't take it there, and so that's what's been happening. And in addition, some of the excess pipeline capacity, and it's not much, has been used to bleed that down. So if you recall from prior calls, we said we thought that there was maybe a 60,000, 70,000 barrel-a-day imbalance. And if you do the math, but if you divide 10 million barrels by 150 days between May and November 1, it's about 65,000 barrels a day. And that means that, that much has been not only pulled down but then, there's more that's been diverted. So there's probably in the neighborhood of 120,000 to 130,000 barrels a day that's been diverted away from Cushing, either by pulling it down or just going around it. And a big part of that's been rail.
