Sure. This is Phil. We have seen, obviously, during the storms and at the beginning of the year, transits were elongated on the rail side. The unloading times were up, which was constraining capacity and drain capacity was at a significant premium, given some of the surges that were out there. We've done a nice job, I think, of making sure that we are sticking with our rail partners and understanding where they have congestion both at the terminal level, as well as online and making sure that we're proactively working through that with them, which I think is part of why we've seen an improvement in transit. On the street, we've done a good job in a very competitive driver market of maintaining our driver force. We haven't added as many as I would like, but we have done, I think, a very good job there. And we've done a great job, in my opinion, of continuing to align with our third-party carriers and ensuring that we have available capacity. There are some constraints on the drayage side, on night and weekend sort of work, right? I think that's where we've seen constraints as we move to a more 24/7 supply chain. That has certainly been something that has been a challenge. But, once again, working with our drivers and our third-party partners to really overcome that. And then lastly, last year, our customers, and early this year, were really struggling with getting folks into work for warehousing. And that was certainly a constraint on capacity, a constraint on chassis availability, which downstream impacts terminal fluidity and online fluidity as well. As the vaccines have been rolled out more broadly, we've seen a significant improvement in folks coming back to work. Something that is still out there, and I think this is the challenge for all industries, is the continued government subsidies where that might not incentivize work long-term. It's a good thing for the consumer, but not necessarily for our unloading time. So that is something that we're closely monitoring with our clients every day. And we, once again, have seen significant improvements from where we were in the fourth quarter and even the first quarter of this year. So all of those I would say are heading in the right direction. I don't see a negative out there for us. Just want to make sure that we continue down that path, and I think we'll be in very good shape to have a strong peak.
