Kimmies and I received two tickets for the memorial site last weekend. The fountains were both eerily peaceful and hauntingly impactful. Each occupies the exact footprint of one of the Twin Towers destroyed in the attacks and, as each tower was big, each cascade is like a cuboid Niagara.... an inverted eruption.....falling 30 feet to a flat basin, and then another 30 feet through a smaller square hole in the centre. For those who have not been, do so. It really is an amazing thing to experience first hand. Above are a few of kimmies' pics and a video from our tour. It is so strange that I can not only see these fountains from my apt, but can actually hear the force of the water too.
