I can take a quick stab, and others may want to, too. The reality of the North American marketplace is that we're an integrated market. We happen to have a 49th parallel and a border, and that causes us problems periodically.
But in the grain trade and in the hog trade, frankly, something called arbitrage happens. If prices get out of line, product—grain—simply moves from one region to another. The amount of pricing differential that can happen is only equivalent to the cost to truck something from one area to another.
So where the operation is most efficient is where your prices are set across North America; then it's based, or arbitraged, off that. It's just as simple as that.
What we would expect to see with ethanol, and what you've seen, is that grain prices in the U.S. have moved up, and they're moving up in Canada. The problem for our grains and oilseeds farmers, and we state it very clearly, is that we need an efficient, effective, profitable grains and oilseeds industry in Canada for us to survive. The currency reality is affecting them as well as affecting us.
