with the wheel clamp on his car, he steals a jackhammer from a road construction crew and uses it to remove the clamp, but damages the car further as well. Homer eventually gets the boot off and races to Central Park and reunites with his family. They get out of New York before nightfall and while driving back to Springfield, the family reflects on their wonderful time, while Homer's hatred for New York remains as debris from a garbage truck flies through the car's broken windshield and splatters across his face. When Lisa asks if they could visit New York again next year, Homer, still fuming after his experience there, tells her he will think about it. Production Writer Ian Maxtone-Graham, a former resident of New York, had conceived the idea of having the family travel to the city to locate their missing car and believed it to be "a classic Manhattan problem". Bill Oakley, who had visited the World Trade Center when the construction of the towers was completed in 1973, suggested parking the car in the plaza of the buildings. Josh Weinstein observed that, "When we realized that there was a plaza between the two towers, we knew it was a perfect spot to have Homer's car." The animators were told to make a detailed replica of the city. David Silverman was sent to Manhattan to take hundreds of pictures of the city and areas around the World Trade Center. When he returned, Lance Wilder and his team spent time creating new scenes and backgrounds, incorporating small details such as signs and hundreds of extras that would correctly illustrate the city. Oakley and Weinstein were pleased with the final results, and both noted that the buildings, streets, and even elevator cabins were detailed closely to their real life counterparts. In the final scene, as the family is seen driving away from New York on the George Washington Bridge, the credits roll with the "camera" gradually pulling back from a view of the car, to a view of the side, and then on to a panorama view of the city; as if the whole sequence was being shot from a helicopter. To achieve this effect, a computer model of the bridge pulling out was made and then printed out. With the print outs, photocopies were made traced onto the animation cels. The process took a long time and was
