Sao Paulo (GRU) is bad. Hills and valleys with dilapidated shacks on all sides.

While I haven't been to BOM, no thread about a sad subject like this would be complete without ranking Lagos (LOS) as the leader (or does this make them a loser?). Shacks built out of multiple materials: wood, tin, aluminum without roofs; shanty towns as far as the eye can see, only broken up by the occasional fire burning in empty lots or groves dotted here and there. Unpaved roads with broken cars and trucks littered on both sides of the (slow) moving traffic. Quite a sight.
