We prefer to drive across our countries by going on the highways to the south, where fuel is less expensive. Years ago we did a lot of north-south travel, on our way to Mexico. In those earliest days, the exchange rate with the USD was terrible for Canadians, especially 2003. Lots of talk around Canada about whether or not we should adopt the U.S currency, as several countries like Ecuador, have done. Traveling through the U.S. from Canada in those days simply meant we didn't linger, but headed for Mexico. Our dollar then was pegged to be valued around 64 cents for a USD. Mexico was a nice change of pace where our money was worth more, and fuel for a gasoline engine was both less and more: lower price (and they used litros to our litres- not gallons) and better fuel - gas was not mixed with "other things." Many things are different nowadays, however.
