 One common sight on the Riverwalk trail is to see many people walking or riding bikes at the same time.The trail serves a dual purpose of exercise/recreation and commuting, since many people have chosen to use their bicycles instead of their cars (which has started to save the City of Windsor money in road repair costs).In the summer, the trail is so busy and so well-used, it can seem "congested" or "backed-up" at times, from all the pedestrians and cyclists.
