It's like no other crowd you've been in, not the ticket lines for a outdoor concert or even the escape crowds at the end , not the crowds lining Broadway to salute some new hero of humanity or maybe just the New York Yankees and certainly not the massive crowds which gather to watch the fire works along the Hudson every July.
This is a moving crowd....it undulates in front of you like some kind of multicolored ocean with completely haphazard waves....when you come over the rise of the bridge and see 40,ooo people flowing, it just takes your breath away at the very moment you need all the breath you can marshall.
So, yes, cameras, lights, whistles, ~~go.
