Can someone please help me find the creepy legend about the couple in the playground at night?

Okay. So there's this old story and I'm sure it's called Edge of the Playground or something like that, but I can't find it anywhere. Anyway, it's about this boy and girl who are going to a school dance in the boy's new car, and when the dance is over they don't want to go home yet, so the boy takes her to the playground of his old school. They're on the swings and this weird creature comes out of the woods and they run away and all that. Could somebody please help me find it? Thanks to anyone that answers.
