However, in 2002 the streets were no longer closed. The City even conducted a TV ad campaign telling people not to come downtown for Halloween. In response to the incidence of thrown bottles, and broken glass, the City Council has established a "Glass Free Zone" largely contiguous with the downtown and the South Campus Neighborhood. The Council activates the "Glass Free Zone" every Halloween and St. Patrick's Day and from time to time at the request of the police when they believe there will be a large gathering of revelers. Most recently, César Chávez Day was added to the growing list of holidays requiring such a response.
