requiring 10-person crews. Almost all of Millennium Park was closed for a day for corporate events in 2005 and 2006. Closing a public park partly paid for with taxpayer money was controversial, as was the exclusion of commuters who walk through the park and tourists lured by its attractions. On September 8, 2005, Toyota Motor Sales USA paid $800,000 to rent all park venues from 6 a.m. to 11 p.m, except Wrigley Square, the Lurie Garden, the McDonald's Cycle Center and the Crown Fountain. The city said the money was used to fund day-to-day operations, and for free events in the park, including the Lurie Garden Festival, a Steppenwolf Theater production, musical performers along the Chase Promenade all summer long, a jazz series, and children's concerts. The name of Toyota, one of the sponsors, was included on Millennium Park brochures, web site, and advertising signage. The closure provided a public relations opportunity for General Motors, which shuttled 1,500 tourists from the park to see other Chicago attractions. Toyota said it considered $300,000 a rental expense and $500,000 a sponsoring donation. On August 7, 2006, Allstate, which paid $200,000 as a rental expense and $500,000 as a sponsoring donation, acquired the visitation rights to a different set of park features (including Lurie Garden), and only had exclusive access to certain features after 4 p.m. The park is closed from 11 p.m. to 6 a.m. daily. Chicago is a dog-friendly city with a half dozen dog beaches, however the city does not permit dogs in the park. Only on-duty service dogs for the disabled or visually impaired are permitted. Surveillance cameras In November 2006, the Crown Fountain became the focus of a public controversy when the city added surveillance cameras atop each tower. Purchased with a $52 million Department of Homeland Security grant, the cameras augmented eight others covering all of Millennium Park. City officials had consulted the architects who collaborated with Plensa on the tower designs, but not Plensa himself. Public reaction was negative, as bloggers and the artistic community decried the cameras as inappropriate and a blight on the towers. The city said that the cameras would be replaced with permanent, less intrusive models in several months; it contended that the cameras, similar to those used throughout Chicago in high-crime areas and at traffic intersections, had been added largely for security reasons but also partly to help park officials monitor
