Possibility Playground is a playground in Port Washington, Ozaukee County, Wisconsin built to accommodate children with special needs and used by children of all abilities. The playground was the brainchild of Mardy McGarry, a special education teacher at Lincoln Elementary School.
With donations from several local organizations and many individuals, McGarry was able to raise enough money for the building materials. The actual construction was done by thousands of volunteers, beginning in September 2008 and completed within six days. Opened in October 2008, the playground has equipment that accommodates the disabilities of special needs children so that they can navigate the playground with ease.
