I took this photo of my humble transport parked in a South African township. On both sides of the photo, one sees the homes of "back yard dwellers" -- in this case, more like "front yard dwellers" -- temporary structures for the poorer folk, and often a source of income for the owners of the property. Nearly 100000 people live like this in Cape Town, my home city. There is an in-depth paper on back yard dwellers at Augmented Informality. OBSERVATION: In fact, one sees back yard dwellings all over this photo.
