I'd just actually like your comment, then, on transportation in the future. Do you see rail lines continuing to be one of the major modes of transporting some of these products? I think we have some of the investors in the States who have actually come out against the pipelines because they have significant investment in the railways. I'm wondering if you can comment on that.
We've discussed the safety of both of these. They both seem to be safe modes of transportation. Do you have any thoughts on that?
