NEW YORK (AP) — Many New Yorkers appreciate the business the United Nations General Assembly brings each autumn.But few will miss the traffic and the sirens and the motorcades and the black 4x4s bristling with single-minded security types.The gridlock can be excruciating, hotel rooms are hard to find.The event draws 193 delegations to the aging U.N. headquarters on the East River. It's tough on people who drive cabs for a living.But it's a love-hate relationship. The many people who house and feed the delegates are thrilled to have so many high-powered guests in the city.
