Pittsburgh shines

Pittsburgh was long known as "Smoky City," with the dirtiest air in the U.S. But the day we got there - the 4th of July, as it happened - the place sparkled. There's a story in Pittsburgh's transformation that I hope to tell in my next column.

Meanwhile, I thought I'd share a few pictures. Above is the view from atop Mount Washington, which used to be called Coal Hill. We climbed the cliff on board the Duquesne Incline, an ancient contraption that is dramatic and a little scary. Below is one view from inside the car. Finally, three 'Burghers celebrating Independence Day.
