Steely sunset

The Midwest is sometimes referred to by an unflattering nickname, "the rust belt," because of the region's former reliance on the dying/dead steel industry. But the metal now proudly on display in Chicago is anything but rusty. Anish Kapoor’s “Cloud Gate” and Frank Gehry’s concert pavilion are magnificent examples of what can happen to metal when at the mercy of masters. Also, Gehry’s graceful footbridge looks like a steel ribbon and provides access from the east to Millennium Park. The park has changed the neighborhood immensely. Over the next few days, you’ll see why and how.
