Cheap potash. Which is kind of a trade, really. You guys got a lot of sunshine. We got a lot of potash. We sell you the potash. You use it for fertilizer and grow all kinds of delicious fruits and vegetables all year round and sell them to us. A few days ago, with four feet of snow in my front yard and the windchill at -38C, I marvelled at the assortment of fresh produce at the grocers'. All fresh and delicious and a lot of it grown in desert soil fertilized by potash from Sussex, New Brunswick. And from Saskatchewan, of course... big potash producer.
