OMAHA, Neb. (AP) — An anti-smoking group behind Omaha’s indoor smoking ban passed in 2006 is commemorating the ordinance’s 10-year anniversary by calling for the ban to expand to the outdoors.

The group, GASP, announced at a news conference Friday that it seeks to have smoking banned in all of Omaha’s city parks and other outdoor city property.

In a written release, the group says it wants the outdoor ban “to protect children not only from breathing secondhand smoke, but from seeing people smoking or spitting tobacco, because children copy what they see adults do.”

The group pointed to an Iowa law that requires some outdoor events like concerts to be smoke-free.
