I have maybe one final point. It's a question that certainly goes beyond my area of expertise.
Environmental standards are different now than they were then. That helps, but it's not the endgame. Also, there wasn't a good understanding of some of the impacts of these things way back when. By example, with regard to Giant Mine, I think people knew there was contamination there, but the assumption was that it was going to stay frozen. It's up north. It's underneath the ground. Guess what, with changing temperatures some of that stuff is starting to melt. All of a sudden the plan has to change in terms of how to clean it up. It's a really interesting area. Things do change. It does come down to what the oversight mechanism is for industries in these areas, which again is not my area of expertise.
