I have visions of the real people of Manhattan blocking the run. Is it Sunday? By Sunday those people will be very angry.
It starts Sunday at 10 or 11 AM. Having done it once, it requires massive logistics as normally it gets about 40K participants. Big deal for the whole city, with that many visitors, for hotels, restaurants, even shows. The runners come from around the world. It should be cancelled.
I think New Yorkers know what to do.
