My time is running short, but I have a very troublesome question that was given to me by Ray Simard and that I'm going to put to you. You can offer a yes or no answer, or you can follow it up. It was a good question.
He asked, is there ever an end to the big science projects, or do you just continue to build, just as SNOLAB was built on what was done before? Is there ever a point at which you say, we've done what we've done in this area and there's no reason to continue?
