Intrepid New Yorker

I did my duty. I hustled downtown, crossed the Hudson River, over the Beautiful Brooklyn Bridge, found a place to park, walked (hoping my car would not get a ticket) around the corner and to the waters edge. And what did I see? Nothing! Well, I did see the bridge, the skyline, a couple of lovers sitting a park bench, bus loads - more bus loads - more bus loads - I had to dodge a bus myself, and stuff. But I did not see any waterfalls! What is the big deal? I know it is public art and I should love it. but "it" was turned off. How can a waterfall be just turned off. There is not a drout.
