looking at the edge of the world

Far away, on the curving, distant horizon, is my home city, Toronto. You probably can't see it, but when this picture was taken, up in our balloon, we could see the CN tower as a tiny, pointy silluette, right on the edge of the world, with a vague hint of the buildings around it. The sun was glaring at us and everything had a yellow haze. It was the most amazing moment of the entire flight.
