I had breakfast on the rooftop of my hotel, which provided a fine vantage point to observe just how horrible the air quality is here. The nonstop blaring of horns--which would have bothered me all night if I were a light sleeper--is something one gets used to, I guess. I got to read all about Federer's 10th Slam title victory--most of which I missed while travelling--in the local papers over breakfast.
