Sure, and certainly I'm going to defer to Alicia here because that's part of the mandate of the document that she spoke to.
In Canada we focus on the creation of the fuel as opposed to the delivery to the customer. It's up to the obligated parties to take advantage of their street corner locations and create their own market niches for one another, but what I will tell you is that in the United States, particularly in the Midwest, you have seen tax credits for pump turnover, you have seen drivers of technology that can be easily communicated to consumers at the pump so that they themselves can make those types of fuel choices in the gasoline market.
But you're right on the nose. Ultimately, if we want fuel diversification, there is going to be an upfront capital cost to implement all of these different fuel choices.
