When I was in school and years later when my son was in school there was at least one broken arm or leg from falling off the slide. Never any serious injuries from the swings. Bumps and bruises are a part of growing up. Our parks here are removing the sand from the play areas--they attract critters that think they are public restrooms. But the swings-merry-go-rounds- monkey bars and slides are still here and they have added the jungle gyms.One of our parks has a miniature merry-go-round and those animals on a spring and a smaller jungle gym for the littler kids.
