That's right.
It's vessels, arrival times. As an example, a vessel may be coming into Ridley Terminals. The industry believes it's going to be there on such-and-such a day, and maybe there are issues on the sea and it doesn't get there for two or three days, so the grain stocks pile up in Ridley.
And sometimes there are space issues. They can't unload the railcars because the terminal bins in Vancouver, Thunder Bay, Churchill, and Ridley are full. That's one thing.
It's very difficult. I'm certainly not an expert on marine shipping, but I know that sometimes the communication there is not what it needs to be.
