Yes. So if you want to look at the Carlisle Mine, this is Brent, yes, when we idled the mine in 2015, we had roughly 88,000 feet of main opened up heading in multiple directions. We idled in, I think, July of '15, we sealed the southern portion of the mine. Then we announced here in our 10-K that in January of this year, we sealed - we decided to seal the northern part of the Carlisle reserve and I don't have that exact number in front of me how many feet that was, but I'm going to say in the neighborhood of 45,000 feet. But it was more than that, we just were having a lot of falls in those mains, and quite frankly, we've - it was becoming a significant safety concern. When we look at the mining costs of that mine, the northern portion of the reserve was more expensive to mine than the western portion, which we have left. So anyhow, we decided to seal that mine off, and in doing so, we really shrink the footprint that we had to inspect and maintain. And going forward, we think our - you now have a mine that roughly only has three miles of main opened up and the mining in front of it looks really good. So I think our cost structure there, when we do fire Carlisle back up, looks something more like it did a few years ago because we certainly - it looks more like a new mine, a lot less out bye to have to maintain. Now we're doing - so we did lose a little capacity. Carlisle went from putting out 3.3 million tons, we think its capacity now is 2.5 million, but we think its cost structures is much more reduced. The part - the second part of your question, I think, was - I think what you're alluding to...
