Sure. So it was interesting in the second quarter. We knew and we talked about this 90 days ago, that the comp if you will, for us it was pretty tough in Q2, coming off something in the mid-three's. It was a great number, it was heavily influenced by handful of markets that were white hot and we were not expecting to do that again and in fact in the case of Dallas, we tried not to do that again. That certainly can create backlog issues that you worry about, both the quality of your backlog, the margins in your backlog, the customer experience. So I'm pleased with the fact that, we have not got it kind of an oddly shaping demand pattern. It feels pretty good across the business. Now that gives us some confidence as we look into Q3. Now your question really gets at this mix between specs and 2B builds. And I'm going to say something, maybe it's because I'm getting old. I can't remember, if I said this way exactly this way in February. But it's certainly been an issue inside the company. There's a certain unintentional or may be not an obvious relationship. As you're emphasizing specs sales in part by pushing up 2B built pricing, that's how you sort of make the specs on a relative basis more attractive. In some of the communities, that hurt sales space. Not a lot of specs in that community, not wanting to get the backlog, too big, too far out. So it's interesting. I think, that there might be a knee-jerk reaction, if you're going emphasize spec sales, that's only going to be positive for pace. It's more nuanced than that and that's why, as I look into Q3 and say, we're going to be a little less aggressive on pricing of the specs. I don't see that having this instant corollary that okay, well that means paces got to decelerate. I think, we can kind of let horses run a little bit in some communities from a 2B built perspective, that we didn't in the second quarter. The other thing that happens every quarter, is there's always a mix of close outs and start-ups or grand opening, that you've got and as we look at the roster of start-ups. I know that we've got pretty good pent up demand in some places interest list, waiting list. Checks in hand in some places, that also gives us some visibility into feeling all right about the third quarter.
