  Word travelled quickly in the small fishing village of Port Washington,

Wisconsin. So when McCarty wanted to build a playground for kids with special

needs. 2,800 people ? a third of the town ? rolled up their sleeves(衣袖)and

helped her.

  "A lot of learning comes through play," said McCarty, 52, a special

education teacher for 28 years. But her students were too often left out. She'd

seen the traditional playgrounds stop wheelchairs dead in their tracks.

  On September 16, 2008, the first day of the project, they came. Two women

heard about the project on the way to work and took the day off to help. A couple

in their 80s took part in the job. Children came and gave a helpful hand. Many

were volunteers. They all worked very hard.

  Today, Possibility Playground is one of the most popular destinations in

Ozaukee County. All children can play shoulder to shoulder. There is special

equipment(装置) in different parts. Here, you see all the kids on the same

playground having fun.

  "People used to ask. 'Why do you want to build a playground just for

children with disabilities?' " McCarty said. "They didn't get it. It's only when you

build a playground for children with disabilities that you build one for all

children."
