Yes, sir.
From a policy perspective, I think the speed at which rail has really taken on an ability to move has caught everyone a bit by surprise. It comes with some of the unconventional development, some of the unconventional development in the Bakken and in other areas in Saskatchewan, for example. It has a field life that's expected to be shorter than that of large oil sands operations, for example, or in the offshore.
Rail is much more efficient for a 10-year horizon versus a 30-year horizon. It adds flexibility. That's the easiest way to put it.
