Yes. I would say that this is probably the strongest and best bidding environment that we've seen in many, many years, not only from the perspective of jobs bidding, because we're seeing Zane, we're seeing some of the bigger jobs, bidding like the Bois d'Arc Lake project that have had a couple of different bids on those, it represents 60,000 tons. But, I think the biggest thing is we're seeing a whole lot of jobs bidding and getting into backlog that are somewhere from $3 million to $7 million or $8 million at a time, which is really helping buoy that backlog and keep it up at record levels. And certainly, as we look at what the bidding program looks like through the rest of this year, we're expecting, as we said earlier in the year that backlog to remain high and relatively stable as we get all the way through this year and actually moving into next year. So when you look at some of those multiyear projects, that you asked in your I guess the initial question, was this Bois d'Arc Lake project goes over a substantial period of time, it's broken really into two sections: One is the raw water line, which is the first piece that was bid that represented 25,000 tons for us. We're going to be running that really through this year and probably into early next year. The second piece of it is the treated water line, which is another 22,000 tons. We'll likely start running that late in the year, probably late November, early December timeframe. And that'll continue well into next year. But, there's also these Houston groundwater projects that are little bit hard to probably quantify because this thing is bidding like $7 million, $8 million, $9 million at a time. So it keeps getting pieced in, but we're going to see those bidding opportunities continue well into next year, which gives probably a pretty good base in the bidding load. But, we're not only seeing those multiyear projects going on, but the expectations that next year bidding is going to be a very solid bidding year after coming off of a very strong 2018 and a very solid 2019. The expectation of 2020 as a solid bidding year really bodes well for with the backlog is in the strength of the business as we go out into 2020 and beyond.
