Okay, fair enough.
Mr. Orb, this issue came up when you were with us before. It's come up again in this current study. It's about the health of our short lines. I know that the Saskatchewan short lines were particularly helpful in terms of illustrating what the situation is. Where do they fit in the grand scheme of things, in that whole pipeline of trade—pardon the expression; it's for Ron's benefit—that goes out to the coast?
How important are they, and how much of a weak link do you think they might be?
