It is said that nothing on Earth can achieve a state of perpetual motion. But I sometimes wonder if New York doesn’t disprove the assertion. Each time I return, the city has always changed, grown and evolved. In the past year it received almost 60 million visitors, and Broadway enjoyed its best season ever in 2015-2016 with grosses of $1.3 billion and audiences of 13.3 million. And then there is the constant physical change. Despite the center of the city being a relatively small island of just 22 square miles, the rate of development has soared. Downtown, work continues at the World Trade Center, while on the West Side a former rail yard is being transformed into the largest private real estate project in the United States and the biggest in New York since Rockefeller Center was built in the 1930s.
