A view of the main street running down Alta Cayma. As the city grows, it expands outwards, and the distance from the center is a decent ruler for measuring socio-economic status. The houses, businesses, and infrastructure closer to the hub are significantly nicer than those in the periphery. Conversely, a view up the street running out of town (from a few blocks higher):
Rural poor come to the city looking for new livelihoods, and the easiest place to start is on the outskirts of town.
Also, a wee little video of the same area.
