On our first day here, we took the Metro (Subway) downtown to the World Trade Center Memorial. Thousands of tourists and service workers experienced the Memorial grounds which includes two separate and large squares representing the bases of the twin towers. The perimeter of the squares includes a tilted continuous metal table with the names of all who lost their lives in the collapse of the towers, including the business people, the firemen, policemen, EMTs, and other service personnel. Inside the squares was a continuous waterfall all the way around the perimeter. Then in the middle of each of the two squares was a large square hole that the water from the perimeter waterfall fell into. The effect was 'white noise' to hush the talking of those taking in the Memorial. In addition the waterfall captured the sense of falling from the towers. This Memorial overpowered us with the significance of 9/11. Our lives were changed forever by 9/11. Our travel, airports, crossing borders, sporting events, in fact any large gathering of people has security to protect us from terrorism. Life has never been the same. In fact afterward we took the Metro to Time Square. Police were everywhere in the crowds of tourists and New Yorkers keeping us safe. Later in the afternoon we went to iMax to see Tom Cruise in 'Mission Impossible: Fall Out'. Great movie! The next day we enjoyed the American Museum of Natural History with its dinosaur displays, its human culture and animal displays, and its ocean exhibits. We were reminded of the movie: Night at the Museum, which took in many of these exhibits. Afterward we headed to the Metropolitan Museum of Art, and took in exhibits that included Impressionist Art (Renoir, Monet, Gauguin), and European Art (Reuben, Rembrandt, etc.). Both museums were in Central Park, giving us time to walk through parts of the Park called the 'Ramble'.
