Urban symmetry at Hudson and W. 14th Street. I always liked this building. I took a writing class here once with the fabulous Laurie Weeks.
W. 14th Street is becoming gentrified in a scary way - designer shops replace streets that felt safe to certain street-roaming types. Now they just feel expensive, i.e. not so safe.
Further uptown a bit, on W. 21st St. in Chelsea, there is a curious building that has many balconies, all closed in with wire fencing and bamboo-looking shades. Altogether unattractive, but attractive just the same.
Sometimes one feels the urge for complete symmetry. In that situation, go to Grand Central Terminal.
