I am Sable, the homing pigeon. I am perched under a large concrete overpass. The traffic appears to be moving on the left side of the road, which is common in East Africa.

The vegetation and the overcast sky are consistent with the climate of the Kenyan highlands. I am fairly confident this is Nairobi.
