"in recent years, empty campuses have been recognized as potential cash cows, and colleges have tried to fill those once-sleepy weeks with enrichment workshops, for-credit courses, day camps, conferences, private parties and film shoots. That is especially true this summer, as financially battered schools seek to wring all the value they can from venerable halls and shiny athletic centers," The New York Times reports. "There is a marketing upside, too, in maintaining a busy campus in summer, administrators say. On campus tours, prospective students and their parents respond better to a vibrant environment. And a high school student who takes, say, a three-week screenwriting workshop might remember that institution when applying to college."
