Trey, thanks for the question. No, you are entirely right to put up these numbers, but as you said, North Carolina is not at peak of its game right now, we think it's going to be back to normal, by the way mid half year, next year, but what we've done in this very impressive quarter is done a good by arm and half tied behind our back because North Carolina is down, but it's not going to stay down. Then Magnesia Specialties is going through the foot moral right now, but it's not going to stay down either. So what you're seeing is really a two-fold impact Trey, one, pricing was very good and that's something that we come to expect and you come to expect as have our shareholders. So there are no surprises there. It's nice to see it performing in resilient fashion. Again, one of your closed down to double-digits on volume. But to your point, I think what we're really seeing, even separate and distinct from the energy piece of it, is very good cost performance and that's something that our team has been focused on, it's nothing that's new to Martin Marietta, you can see it also in the SG&A numbers. But if I go through and look at where we'll be not just in energy, but where we'll be relative to contract services, repairs, supplies, and other plant costs, all down, and that's exactly what we would anticipate. As you recall, Trey, we've gone through cycles. We tend to invest very carefully in our company. And when we were going through the financial crisis in the Great Recession, we did pull back on CapEx. At the same time in the last few years, we've taken CapEx up and that has truly been an investment in our business. So what we're seeing the benefits of is a better cost profile, operational excellence, cost performance across the spectrum that we would anticipate. And the other thing that's important, Trey, is the way that we've grown our business. So when we've added businesses as we have in Colorado and what we've done in Texas with TXI and what you're seeing from excess real estate sales and similarly, what we've done with Bluegrass, these have all been enhancing this organization, but it's truly aggregates led and you're seeing good performance come through on the cost side, which again is exactly what we would have expected. And the thing that I've really enjoyed and I am so grateful with this team on is continuing to show their agility and being able to manage that on the fly and as they would need. We're always going to remember 2020 as the year that could have been, because if you're seeing this type of performance with volumes down, you can imagine what I believe we'd be doing this year if we were not in the midst of the pandemic.
