Well, a hard question to answer. I mean, certainly, the last, at least five years really since about 2009, 2010 period. Vacuum truck demand for both sales and rentals has grown very healthily. I think it was, certainly the governmental portion of it has been stable and steady and going up some, but the nongovernmental portion, that used everything from construction, oilfield, mining, general industrial applications, has shown very good growth. Those are the industries that are - some of those are down, mining is down, oilfield is down, construction like you said, looks like it's weakening. And so, those are the areas that have been most affected. So like I said, we benefited from multiple years of very strong growth in that sector and so probably the industry got a little bit ahead of itself. So now that the demand down, but probably there is supply is that, there is a lot of trucks available. So I think there are two things that have to happen. Number one, a bit of overhang of trucks that has to be worked down, which will probably take us into next year. And then, we hope to have some pickup in some of those other areas, like oilfield, mining, so even construction activity I think, which is - as I said, sort of seeing some slowdowns in the U.S. as well. So I mean, I think like you said, once the little bit of the overhang, next year, I think we'll start seeing some improvement in the market, but I think it's going to take some improvement in the general economy before we're going to see why it's back to the kind of growth in the non-governmental sectors that we saw previously.
