This is a great biography of New York and its subway system. In looking at the subway from many angles we not only are reminded of the magic of New York City but also get some insight into human behavior and urban culture. You certainly are not limited to broadcasting this in NYC. This piece has universal appeal. The sum of the parts, however, is greater than the whole. There is almost too much to process in this hour-long format. The segments are much more effective if you listen to them in isolation. The cumulative effect of listening to the segments leaves you with a greater appreciation for the life of the subway. In the hour-long format you are likely to miss a stop or two. The individual pieces would be ideal drop ins for ME or ATC.
