Other colleges across the country have gone on high alert around St. Patrick's Day to deal with alcohol-fueled students. At Penn State, the school paid licensed liquor establishments to stay closed this month during the unofficial drinking holiday known as State Patty's Day for the second year in a row.

State College, Pa., police Chief Tom King said that the strategy, along with a fraternity ban on parties, helped lead to a 75 percent decrease in arrests and citations this year compared to 2011 — the fake holiday's heyday.
