Sure, Kathryn. Good morning and thank you. As we look at next year, one of the key drivers in our mind, Kathryn, is simply taking a look at where our customer backlogs are at this time of year versus where they were last year. So to give you a good sense of that, if we're looking at Q3 2019 backlog in Mid-Atlantic, our customers, it looks like were up about 57% versus where they were last year in backlog. If we're looking in the Midwest, major project backlog, looks like it's up around 11%. Similarly, if we look in places like the Southwest, and ready mixed backlogs were up 12% driven by market growth in both the North and the South, and then to your point, cement backlog from what we can tell is us up over 65% driven by major project work, and that includes large DOT projects, Kathryn. So as we look at what our customers are telling us, that's giving us the confidence going into the new year, it's the same type of thing we're seeing in Colorado right now, Rocky Mountain customers are saying their backlogs are up around 12%. So as we look at where the growth is coming, as we indicated we see infrastructure better, we see non-res better, we see residential better next year as well. Specifically, with respect to cement, as I indicated, a lot of it is major project driven. That's very healthy both in North Texas and in Central Texas. As you recall, the two cement plants we have are in Midlothian in North Texas and Hunter in Central Texas. Part of what I think is important in that marketplace too is what we're seeing relative to pricing in 2020. We have put out our pricing letter for next year. We're anticipating an $8 a ton increase in Texas, that's going to be effective April 1. So again, if we look at volume across the aggregates business, we see it being widespread and we see it nice and steady, and we see good customer backlogs. We see the same thing in cement. And again, this is going to be more driven by public works we believe in Texas. And again, we think the pricing environment as we go into 2020, as I indicated in the prepared remarks, both in aggregates and cement looks better going into '20 than it did coming into '19, and it looked better coming into '19 than it did coming into '18. So a long answer, but I think you need that color on where the volumes coming from and how we see pricing as well.
