I think the best reason would be grain not being in position to be loaded. Something such as a railway strike, an avalanche, or an act of God that was completely unpreventable might have happened, so we have to be aware of those things.
There are also things like the loading of the ships. If it rains in Vancouver—which it does; we checked. In Vancouver, about 20% of the days have over five millimetres of rain. It doesn't rain all day, but you have to be able to address those problems, whether it means putting tarps over the vessels or using smaller spouts. It's a problem which is being addressed around the world. It seems that the safety concern is something of a red herring. You go into work, work for 15 minutes, and it starts to rain, which it does in Vancouver every day, and then you go back to work when it stops raining. It might not stop. All of those costs are passed back to exporting farmers.
