THE smiles on the faces of the William Stimson Support Unit pupils told the story: they love their new playground.
The Wetherill Park school was the beneficiary of Mounties' inaugural Charity Race Day at Hawkesbury Race Club last May.
The Mounties Group donated $66,128 to build the undercover playground that includes a slide, swing and all-weather surface.
William Stimson Public School principal Jan Williams said: "We're very grateful to be the first recipient of the Mounties Charity Race Day.
"Something as simple as having the opportunity to play can have life-altering impacts on those with disabilities."
The Support Unit was established in 1989 with two classes for students with a physical disability.
It now has seven classes and caters for 46 children, aged from 4½ to 12, who have been diagnosed with a range of disabilities.
Mounties Group president Kevin Ingram said the new playground would give young people with disabilities the same opportunities to socialise and explore as their able-bodied classmates.
