Many college towns have tried to limit the availability of alcohol off-campus. Here are a few examples:

— In Madison, Wis., the city council clamped down on new liquor licenses near the University of Wisconsin campus.

— The University of Iowa sought legislation to reduce the number of bars and liquor stores downtown.

— The University of Nebraska-Lincoln pushed an ordinance banning after-hours "bottle clubs" that give drink mixers to people who bring their own alcohol.

— Newark, Del., placed deed restrictions prohibiting alcohol sales on three properties near the University of Delaware.

— American University in Washington, D.C., has worked with police to "ensure that local bars are not serving underage students, promoting binge drinking, or operating unlawfully," said Mary Kennard, American's general counsel and incoming president of the National Association of College and University Attorneys.
