On Friday and Saturday, almost every regular trend from past Unofficials held: a high ratio of non-University students ticketed to those given to University students (about 3-to-2), large number of minors ticketed, huge parties raided (a record-high bust this year netted 69 violations, 61 of them for minors in possession — that’s $19,520 in tickets).

But the most unmistakable trend was weather’s effects on the Unofficial festivities, which may have been the factor that significantly reduced the number of violations recorded that day.

“At least in the early morning and afternoon hours, because they noticed weather was fairly cold … more students may have decided to drink indoors,” said Roy Acree, University police captain. “I’d say this year was primarily weather-driven, compared to last years.”
