I'll take a cut at that. As you look at it and as we've talked about, our demand profile has been very strong across virtually all of our markets. We feel really good about our products. We feel really good that we're winning in the markets, and so you can see that in the very elevated bookings and then, obviously, very elevated backlogs. So, we actually believe we're going to go into 2022 with a very strong backlog position, much stronger than normal in a number of our businesses. If you get to the underlying demand of what we are seeing, what I would say is, if you look on the cooling side, which really serves a wide variety of end applications, from data centers, schools, government, commercial, all across, we're actually seeing very positive indicators. And if you look at the areas we track, the Dodge report of new starts, you look at their predictions for 2022, I would say that would lean positive. So, we're seeing some positive signals on the demand side on the cooling side. A chunk of that would also pertain to the heating side. As a reminder, most of our hydronic or boiler business is more replacement, but we feel really good with where we are with our products and our market share strategies there. In particular, our contactor program. So, I would say on the HVAC side, we feel good as we look forward to 2022. As I look across our D&M, I would say, on location and inspection, we feel good. We've had some really nice bounce back from radio detection, which is our largest business, and we're just seeing really nice momentum in there and we would expect that to continue. And you look at the other components within there, we see some continued growth going in. I would also expect AtoN to see nice growth as we go into next year. And then, as I look to CommTech and transportation, we do expect growth. I would say, I'd probably expect more moderate growth there in those platforms. So, at a high level, we feel good about the general demand profile and we feel, ironically, that the situation we find ourselves in is we're winning in the market and our new products are doing very well. We have more demand. The demand is just outstanding. And I guess, like a lot of companies, a tremendous amount of our time is focused on the supply side and that would include supply chain as well as some labor. So, a little bit of that slipping out should give us a little bit of benefit as we go into 2022.
