What I'm thinking of first is hanging campaign posters in all the hallways, where most of the students are sure to see them.M: That sounds good. But everyone puts up posters. What can we do that's different?W: The campus radio station is willing to let you have five minutes tomorrow morning at seven o'clock to outline your plans for the year. Lots of students will be listening then.M: That's a great idea!W: I've also arranged for you to give a speech during dinner tomorrow. At least five hundred of the students will be there.
