This is the same haze that I see everywhere I go, Denver, New Delhi, Kathmandu, Chicago, Boston. Maybe it is dust, surely some is pollution, maybe it is fog, in fact in China apparently they call smog, fog. Whatever it is, it is pervasive. Things don't seem to ever fade into the distance with the curvature of the earth, but fade into the haze. The part that makes me sad is, I don't think it was always this way.
