Description & Facts: Calgary is an oil capital and commercial center, with a rapidly growing population of young professionals attracted by the vibrant economic environment. It takes just a little over an hour to drive to the Rocky Mountain resorts in Banff National Park. Calgary has grown around the intersection of the Bow and Elbow rivers, and the city is divided into a four-quadrant grid, with the Bow River separating North from South, and Centre Street-Macleod Trail.
