Well, I think that we did -- we moved a unit of people from Oaktown to Carlisle. On the tonnage side, I expect things to be, as far as capacity-wise, one unit in Carlisle, they're a little smaller than a unit at Oaktown just in how they're set up. We will not run as many days. Our current plan is not to run as many days in the second half of the year just due to holidays and probably less weekends, depending on what our sales position looks like. We wanted to build our inventory this year as we said we would. Quite frankly, production at Oaktown was remarkably good. And so we will look to draw that inventory level down as the year goes on. So, part of that's going to depend on what our sales look like for the balance of this year. We think the market has tightened up quite a bit because a lot of tons have gone to export that were not anticipated and we've had a good heating season this year. So, all those things, we think as the year winds down, we think that we have several customers that will be in the market looking to purchase spot coal. How successful we will be on those bids, time will tell. Looking to next year, as we've said before, we think that it's going to come down to buying season. But we think because of the Princeton Loop, we're talking to more customers than we have in the past. And so we think our potential for more sales is greater in 2019 than it is in 2018. The back half of the year, if you look at this, we're going to be shipping -- contractually, we're scheduled to ship at a 7.6 million ton pace -- excuse me, 7.8 million ton pace. And if we make additional sales, that's going to push us potentially to be running at a pace up over 8 million tons. So, we would need to run Carlisle to be able to hit those shipments because we're bumping -- that would be bumping up against Oaktown's capacity. So, we think we have an opportunity to keep Carlisle running next year, and we hope to be adding units there. But ultimately, it's going to come down to what the market needs us to do and what qualities the market needs us to do. We've -- the quality we get out of Carlisle is very similar to Oaktown 1 and 2, but it is a little less -- a little lower sulfur. So, when we ship to those Southeast markets, typically, that coal mill will come out of -- or it can come out of Carlisle if that's what the customer desires.
