Calgary has developed a unique habit when creating new neighbourhoods as the city expands. In the south of the city they dug a huge hole, made a hill with the dirt, made a lake in the hole and then built a neighbourhood around the lake.
The result? Fascinating lessons in modern urban planning. Check out Lake Bonavista, Lake Bonaventure, Lake Midnapore and many others if urban planning is your kinky thang.
The above mentioned neighbourhoods are south of the city centre.
