The Mason Parks & Recreation Foundation has been diligently working toward the building of an inclusive playground in Mason, called Common Ground. This playground will be the first of its kind in the area in both size and scope and will meet the needs of children and adults with all mobility, sensory, sight, hearing, and social challenges. All playgrounds are not created equal, and EVERYONE belongs in a unique, engaging and inclusive recreational environment created through COMMON GROUND.
