I'm trying to imagine a high school having a schoolyard. My high school had a track, tennis courts, a football (US kind of football) field, a soccer field, vollyball courts, a courtyard that was used as an outdoor smoking lounge, and a lot of parking lots, but no place that would be called a "schoolyard" or even any part of the day when the students would go outside in a groups to collectively hang out like we did for recess in elementary school. We didn't have anything like that in junior high (now called "middle school"), either.
