Where's the fire?

This morning my walk to work was disturbed by loud sirens, hurtling fire trucks, screeching police cars and not 1, not 2, but 5 of these NYPD tricycles trying to keep up but getting stuck in the hordes of pedestrians. It must be very embarrassing to be relegated to tricycle duty.

And I still don't know what was going on. I've been scouring the news but have seen nothing. I think a fire was somewhere on 44th or 45th Street past 7th Avenue.
