That's an excellent question.
We see parallels, not just in terms of people but also in terms of equipment and supplies. Any industry that uses the same sorts of skill sets that we have would also include, for example, any other resource development, any other energy development, and so on. So we're looking at the same kinds of pools, on the one hand.
On the other hand, as the industry increasingly moves toward more automation, we're facing a future that will be characterized by smart grids and electric vehicles, and so on. There's a part of the business that's also increasingly becoming high-tech. Not only are we competing, for example, with other construction projects on our hard assets, but we're also competing with Google and Intel for some of the smartest people we're going to need to be able to develop that smart grid for the future.
The challenges are really across the board. It isn't just the people who are pouring the cement but it's the people who are going to be developing the apps that are going to really manage our energy use in the future.
