Let me just say a few things here that I think are vital.
One is about those investments that have already been made, and those that we may yet want to make. We're here representing investments that have already been made. These are the consequences of investments in our scientists, in our students, in our technical staff over many years. It's not by accident that we have $100 million to build NEPTUNE. It's not by accident that SNOLAB has been built. It's not by accident that we have a long-range plan for astronomy and the observatories that are associated with that. These are results of strategic investments over many years.
I think your question is a very good one in terms of where we go from here, in terms of what other facilities we would contemplate bringing on stream. And that's a very real and important question, because I agree with you entirely that we cannot afford to try to be all things to all people. It would be ludicrous, both economically and otherwise. But for the facilities in which we already have the international leadership, let's back it up and make sure we fulfill them in a way we can be proud of.
