Monica Crowley and Curtis Kuby on WABC just said 250,000 as an estimate.
given the weather, and the street closures, alot of NYers are going to come out just to walk around in this. so the crowd will be large.
I don't believe it. I'm in an office at 7 and 53rd, and looking at a live webcam on 8th & 34th (there don't seem to be any 7th Ave. webcams, unfortunately). If there were 250,000 people marching up 7th between 14th and 34th , I'd being seeing/hearing some signs, cause there's no way 250,000 people wouldn't be overflowing that route. I haven't even heard a single siren all day!
