The meat packing district used to have a trainline running right through it, they finally put the trains overhead when a little boy got hit by the train, and he became the face of a reform campaign. Things like the Brooklyn bridge would still be there, the Statue of Liberty, grand central, but most ground level districts are so transformed. It depends on the individual. By 1916 things were accelerating and people were being defined by war efforts so I think they would be very surprised and interested in the outcome of the wars, the disease, the killing, the lense through which we viewed those nation defining efforts. I really do think taking a war era person to a supermarket and showing them bananas and piles of fresh food and meat would blow their minds. My nan in law is in her 80s and talks about Bananas being exotic when she was younger, and chicken, Roast chicken was rich food and today its common, and cheap and produced via intensive production. Our Poverty and their poverty would be different things, I was reading an autobigraphy of a local guy, who was welsh, talking about his childhood in the 40s, he never had a set of long pants until he had a job to work, his dad drank all their money and they all caught food.
