I don't know if this happened earlier and you all have moved on but Drudge has a story about a sweet smell in Manhattan. So far the testing has shown nothing harmful.
SNIPPETS::The aroma not only revived memories of childhood, but in a city scared by terrorism, it raised vague worries about an attack deviously cloaked in the smell of grandma's kitchen.
The odor was first detected around 8 p.m. on Thursday in Lower Manhattan. It seemed to spread quickly uptown and into parts of the other boroughs - so quickly that officials expressed concern. The city's Office of Emergency Management sent out feelers to the Police and Fire Departments, state emergency response agencies in New York and New Jersey, and the United States Coast Guard, which communicated with tugboats and container ships at sea to determine whether the odor was being detected there.
