You hit on a whole host of answers within your questions.
First of all, on the charting, the general consensus of the coast guard is that we've got charted to modern standards approximately 5% to 10%, which means that we've got 95% to 90% that is not properly charted. So, you need to chart. The bottom line and the real quick answer is that we need to start treating the Arctic like we treat the Atlantic and the Pacific coasts. We need that type of relationship. We need that type of regulatory regime. The challenge we'll face is that we do not have any of the infrastructure along a vast area of what constitutes the Arctic to the degree that we have on either the east or west coast. So, you're also going to have to start addressing the infrastructure issue because eventually you are going to have port facilities that go beyond what we see in, say, Iqaluit or Tuktoyaktuk or any of the other regions that we do use as some sort of point of refuge. When the ice goes we are going to have to address that.
