Hi: I hope someone can help me. Many, many years ago I lived in Brooklyn and worked in NYC. I rode the Sea Beach line to work at 250 Park Avenue from the 86th Street station in Brooklyn - it ran along Fourth Avenue. It was all underground except for going over the bridge (was it the Brooklyn Bridge - I always thought it was). I do not remember the station where I got off the train and I remember going to the Grand Central shuttle over to Grand Central Station and at one point I walked through a pedestrian tunnel there to an exit which took me out - I thought - at 57th Street and Park. Is that possible? I do not remember what the side street number was. I keep thinking about this and trying to figure it out with no success. Can anyone help me on this. My memory - at least in this case - is shot!!! Too many years ago. Thanks for listening - Gladys Gladys Jensen in Colorado
