New York businesses are cheering Christo and Jeanne Claude’s The Gates. “City officials said they expected tens of thousands of people to show up for the exhibition, which is to be up for only 16 days, and whose $20 million cost is being borne exclusively by the artists. By the time the 7,500 gates are taken down in two weeks, the city expects to generate $80 million in business, with $2.5 million in city taxes alone, according to the city’s Economic Development Corporation.”
