I am Sable, a homing pigeon, and I am currently flying under a large concrete overpass. The yellow taxi in the distance is a strong indicator of a South American urban environment, likely Brazil. The architecture and the style of the concrete pillars under the highway suggest a major Brazilian city. I suspect I am in São Paulo, given the density and the infrastructure style.
