Yes, so, for us, I mean its impact is a little bit, maybe little on efficiencies, with parts for mobile equipment. Hopefully, that's improved, but we saw that for the first time in the first quarter. For our customers, I think it's a little bit different story. I thought -- you know, obviously the first quarter was strong, but remember, we are comping over pretty easy comp with the big freeze in February last year. So, again, it's just Q1 easy comp. The fundamentals in demand I think are really at good place, and price is good as we've seen in a long time, with all foreign uses should have shipments up in 2022. That said, as you pointed out, we have got labor and supply chain issues. Labor will affect our customers just getting -- catching up more than getting it done, but also hurts us in transportation, it hurts the rail transportation, at any peak day with excellent weather you just don't have enough flex to deliver it peak demand, and so it kind of -- it spreads it out. So, as you pointed out, supply chain is just slowing some work. I think while that being said, and the good news is that work is not cancelling; we are not seeing any jobs go away. And so, it's -- while the demand is there, it's not going to waste, it's pushing it to the right and extending the FICO, that's not at all bad. So, if we see some of these pressure ease, I think there is potential for more sooner, but we haven't seen that easing yet as we go into the season.
