It was a really gloomy day, the day I entered Pittsburgh. Again, my prime motivation for visiting was to get good pictures of the amazing PPG tower, a tall, soaring building that one might describe as a "glass castle". PPG Place, with its pointy turrets, it like one big sheet of fine hand-crafted glass, its surface not unlike that of an antique cut-glass pitcher. On the exterior, there is no color variation or added ornamentation. It's all glass, just as one might expect from the company that calls this building home, Pittsburgh Plate Glass. I have been fascinated with this structure since the first moment I saw it. And of course with this being such a noteworthy place, the guards were concerned with me photographing it.

The main body of downtown Pittsburgh rests on an isolated piece of land, being the point where two rivers come together, the Allegheny and the Monogahela. Therefore Pittsburgh has a lot of bridges. So many, in fact, there is a major website devoted to them all: pghbridges.com.

Popping onto the "island" and back off again, I settled on the north side of the Allegheny looking south towards Pittsburgh proper. This gave me a good view of the city and its collection of bright yellow bridges. "Why yellow?" I asked myself. Well, that turns out to be one of the official city colors, the other being black. This side of town was also home to PNC Park, the stadium where the Pittsburgh Pirates play. Outside the ballfield were several statues representing famous baseball players. These were part of a much bigger collection of outdoor art that happened to line the edge of the river.
