Let me hop on that and say that the west coast is different.
Our antennas are closer together, in the main. Our topography is more challenging, and our traffic tends to be a bit more concentrated, especially from Buoy Juliet to Vancouver and near Prince Rupert. That's obviously where we focused our level of effort and energies. We have some differences. The fact that we're microwave-intensive has been part of the challenge.
There are coastal aspects to this project that have emanated.... I'll come back to the point that when the echo, or the time delay, manifested itself in Rupert, it generated some frustration there. We put the brakes on moving into Victoria because of that, and we worked very hard to essentially put in a time delay from antennas so that the echo would no longer be apparent.
It was a technological change. When that was resolved to the satisfaction of my operators, we then decided we could make the shift.
