Gretchen, a student at Maltby Intermediate School, proposes putting advertisements on the school's blue, dull lockers to liven them up. She was inspired by a school in Minnesota that posted ads on their lockers for extra funds. Gretchen believes ads would make the lockers less boring, easier to find, and bring money to the school from businesses paying for the space. She provides examples of the decorated lockers in Minnesota and hopes the idea could spread to improve locker areas in other schools.
