I was born on the Lower East Side of Manhattan (the corner of Rivington and Allen Streets). I lived atop a five story walk up and would spend untold hours staring out the window....... (was better than TV).
Unlike friends that grew up in more rural areas surrounded by trees and rolling hills, my comfort was gained from viewing the bridges and sprawling rooftops of New York City.
Water towers...... as much as anything piqued my imagination. They were majestic, dark, mysterious...... I knew what they were called but there was no external indication of how they worked. I was always suspicious. I would sumise that they would be a great place to hide or even live. There was one across the street (photo above) but none on my roof...... where I could get my hands on it. Alas I am older and have google so I now understand how they work and except for some birds and rodents nothing else hides in them...... no elves or trolls. Though, I remember hearing someone threw a party in one somwhere in Chelsea not too long ago.... thats New York City for you. Anyway I can't imagine my home town without the forests of water towers coming to mind. Hope you find them as beautiful as I do.
