New York City lawmakers voted Feb. 2, 2011 to ban smoking outdoors in public parks, public beaches, and even Times Square. The Big Apple is the latest major US city to prohibit smoking in parks and other public spaces, adopting laws that are tougher than its home state's. Such laws are a boon to public health and reduce litter in urban parks, say supporters. Critics say they are yet another instance of "big government" encroachment on personal freedoms and are almost impossible to enforce. In all, almost 500 cities, counties, and towns have banned smoking in public parks. Here are five big cities that have done so.
