City life is busy in itself, but this activity also has a significant impact on the surrounding areas, as business and personal traffic move in and out on a continuous basis. I've tried to convey that sense of activity, and to some extent the speed of it, through this composite. Multiple photographs taken in several cities but the focal point is no doubt the Gardiner Expressway leading to downtown Toronto. If you look carefully, you'll find details from several industrial areas, a little bit of conservation, as well as housing. There is one other element though, that doesn't fit into these groups. Can you see it?
