Bob, two extremely important things to point out to you, since you are not familiar with NYC. First, Manhattan has tons of trees! There are few trees only in the areas that define the business hubs (Wall Street, Times Square, etc) I lived in three vastly different neighborhood in Manhattan, always on a tree lined street! Second, NYC refers to all five boroughs (Manhattan, Bronx, Queens, Brooklyn and Staten Island) and there are far more tree lined areas than ones with no trees. Whatever argument you’re making for NYC not being a representative case of the USA (which of course it isn’t) the examples you use, including the silly trash one, don’t make the point.
