Yes, I think its worth noting that Dc's decision is an insult to U.S. consumers and Canadian exporters;

MB once had more peculiar problems in Europe where, say, a car exported to the Czech Republic from Germany then imported by an Italian dealer would do strange things to the price after all the currency twists were factored in, but they solved the problem with the Euro dollar. However, North America has only 3 countries to worry about and the U.S. dollar really is the worthy currency of NA, hence we have no need of an uber currency to mitigate periodic price wavering.

One day perhaps all of north america will use the u.s. dollar, but i think at least some bill denominations should include renderings of Zapata or the Queen to reflect the history of mexico and canada (didnt the us at one point fight a revolutionary war aganst the british crown?)....just joking
