The Powers that Be in NYC are estimating that a crowd of 3.5 million people watched the Yankees’ parade in Lower Manhattan.
According to news accounts, the parade route is less than a mile long. By some rough calculations, that would mean people would be standing over 600 people deep on both sides of the street, assuming you give everybody 2 feet to stand.
I have heard that the city includes people watching from windows of offices, but I think that this number is grossly exaggerated.
There looked to be a lot of people there, but 3.5 million people is liking taking everybody in Manhattan and Queens and stuffing them into a one mile stretch.
