I'm not sure we'd write that as a big concern, but I will comment very briefly on violence. We've been very fortunate in our relationships over a large number of years. We just have not had that kind of violence, and we would hope that would continue.
Unfortunately, particularly in the last few years, we've had a number of incidents where our operations have been disrupted for native protests and other reasons. In those circumstances, when you do disrupt service, we have had some grave concerns that the situation could easily deteriorate into a matter of violence. This is something we've spent a lot of time on, in working with first responders and others to make sure those sorts of situations don't happen.
