Yes. No, I think it's been Dave from my perspective, a fairly predictable and I think in large measure because we went for such an extended period of time, without more money coming from the federal government in a meaningful way on that. So, if you think about what happened, we had a decade plus of continuing resolutions. Then we had the FAST Act, that didn't have more money, but it did have more time. And so now what's happened is, you've had that very attractive double whammy of hey, here comes more money. Here comes more time. And you also had DOTs who had actually been building up their own budgets, for about 15 years because they weren't getting more money and more time from the federal government. So I think what we're going to see particularly in Martin Marietta states is, it's not so much driven by maintenance and repair. It's going to be more driven by bringing in new capacity. And that's important for a number of reasons. Number one, our states have had a lot of people move to them. So, if we're simply looking at overall population trends, I mean it's pretty eye-popping to think about the fact that, Texas has led all the states and population gains over the past decade adding four million people. If we're looking at Colorado, their population has grown 14.8% just since 2010. And mean North Carolina has been one of the fastest-growing states in the country. Georgia is going to move up to number 8 in the country in population. So if you think about, why these states need to add capacity, as opposed to maintenance and repair. That's a big reason. And if you're thinking about what happens from a lag perspective, on rather than putting new asphalt, on top of old asphalt but rather adding a new lane or building new roads, it frankly takes a little bit longer. Now, the punchline is it ends up being considerably more aggregates intensive. So, for us, it's like a big birthday. It's worth the wait sometimes. So, we feel like good things are coming from this but I think that's really driving that lag that we've seen the dollars are there. And you can see where they are. You can see what the state DOT budgets are. But again I think it's those states those budgets those population inflows that are driving a different nature of construction. What we'll see in Charlotte, what we'll see in Atlanta, what we'll see in Dallas is going to be a very different story than what you'll see in New York or what you'll see in Chicago.
