Certainly a lot of those communities are accessible only by air. Once again, there are no roads to connect them. Our industry is dependent on those kinds of services.
Other types of mining operations that we might be looking at are also dependent on rail service. So there are many, many different linkages that we have with those kinds of services.
But the impact on other stakeholders, I think, is extremely important to our analysis of this legislation. It's not just an impact on our bottom line; it's also an impact on the communities we have obligations to. We care very much about the sustainability and the benefit of those communities, and we can see a lot of negative ripple effects on those communities as a result of work stoppages that would get much, much worse as a result of this legislation.
