The same thing applies to all other commodity groups. If you have a mine, for example, and I'll hypothetically pick a coal mine that is producing two million tonnes a year, you're taking a truck down a road to the coast, I'm going to guess every 30 seconds, 24 hours a day, 365 days a year, from a mine that is probably located either in British Columbia or northwestern Alberta. Practically speaking, you have to give your head a shake. It just doesn't make sense.
