Southern Ontario is connected by a series of highways/freeways called the 400 series, which intersect at various points and link all the major and medium sized destinations in our small, densely populated corner of the world. The ability to drive on one is what separates the introductory level drivers (G1, the equivalent of a learner's permit elsewhere) from the intermediate level (G2.) And confidence in your ability to drive on them is what separates those drivers from the permanent class (simply called G.)
The first time I ever drove on the 400, it was a pitch black freezing rainstorm in February. I had been out with my co-workers from the bookstore, holding our long-delayed Holiday bowling party. One of the girls, Sam, had recently moved back home with her mom and wasn't ready for the party to end, so two of our coworkers and I were persuaded to keep it going by hitting a pool hall and drinking away the winter blues.
