Newscopy: "When city offered Mission Park as a noontime picnic ground for Mission High students, they formed a clean-up committee, headed by Phyllis Cassidy, center. 'Like a giant vacuum cleaner, the committee goes over the whole park to see that no one's left any trash.' For a week's 'clean' score, school's out a bit earlier on Friday's. For violations, the bell rings late. With Phyllis are Dale Scholzen, student body president (left), and Ed Johnston."
