We don't particularly talk about energy independence because I'm not sure exactly how you would define those words. We have the tremendous opportunity to be more energy self-sufficient in North America. I think two of the biggest obstacles, obviously, are improving the energy infrastructure among our countries, and secondly, getting public support, quite frankly, for the kinds of energy opportunities that we have. I'm not now just talking about pipelines. I'm talking about building up all the renewable energy assets that we have as well. It's getting approval for wind energy projects and for transmission lines that will connect cleaner forms of electricity with the markets for them. Those are a couple of the biggest obstacles.
