Of course, as I mentioned, our terminals are connected to the rail lines. If the rail lines are blockaded, after a significant amount of time, as you heard, everything backs up onto terminals. Terminals are not intended to be warehouses. That's where supply chain challenges occur.
I believe it is four or six days of rail shutdowns that instantly can compound the challenges in the supply chain. There is existing capacity of probably about three to four days in terminals to absorb rail shutdowns. After that, you will start feeling it in the supply chain. If that occurs again for a longer period of time, we will probably have the same results.
