All I know about 1970s New York City is that it's where I grew up, and you always have an umbilical connection to the time and place of your growing up. It was cheap, didn't have too many people in it, you could go to the movies or whatever on the spur of the moment, you could get by without working too much and especially without involving yourself in the corporate world.
Someone once said that middle age is like rereading a book that you haven't read since you were a callow youth. The first time around you were dazzled by impressions, emotions, and tended to miss the finer points. In middle age you have the equipment to see the subtleties you missed before and you savor it more slowly.
