I just wanted to offer a quick comment, which I hope is clarifying.
When you talk about industry, that's not the situation we're facing. We have five salt producers in Canada. That's all. It's easy to enforce against them. That's not what we're talking about. We're talking about thousands of agencies and tens of thousands of operators who are actually putting the salt into the environment. That's where the “enforcement” has to be done, and that's where you have thousands, and those occur in different snowstorms, with different approaches.
