How does Nick describe New York city in the beginning?

In Chapter One, Nick describes New York as the perfect place to learn the bond business. He describes the East and West Eggs as follows:

It was a matter of chance that I should have rented a house in one of the strangest communities in North America. It was on that slender riotous island which extends itself due east of New York — and where there are, among other natural curiosities, two unusual formations of land. Twenty miles from the city a pair of enormous eggs, identical in contour and separated only by a courtesy bay, jut out into the most domesticated body of salt water in the Western hemisphere, the great wet barnyard of Long Island Sound. They are not perfect ovals — like the egg in the Columbus story, they are both crushed flat at the contact end — but their physical resemblance must be a source of perpetual confusion to the gulls that fly overhead. To the wingless a more arresting phenomenon is their dissimilarity in every particular except shape and size.
