Thank you, Mr. Rogers, for the question. I would agree with David. In fact, the rail blockades occurred prior to COVID, and we saw the resulting effects of the blockades for weeks on end.
We have learned some great lessons from COVID, and there can be lessons that will help improve the supply chain going forward. I mentioned the relaxing of some of the regulatory issues. The regulatory release we had was very helpful and was very important, because in the case of railways, we were considered essential services. We continued to run from day one of COVID, but we had to make some adjustments. All the railway companies made some adjustments, but the federal government also stepped up and provided some regulatory relief. So I would say that it goes well beyond COVID, but there are some lessons to be learned from COVID that could carry us forward and maybe improve the supply chain going forward as well.
