Yes, they move both ways, which is interesting.
It brings me back to the science and innovation and competitiveness theme. If we make our farmers more competitive, even here in North America, that would help us with exports, to the U.S., for example. We're already selling into the U.S., so obviously the obstacles are not insurmountable. It's a question of gaining an edge and then keeping the edge, either through the application of science and technology or by always moving ahead with science and technology so that we're always at the forefront of it.
