Like it or not, the day after the Super Bowl is not a holiday -- though judging by pictures coming out of New Orleans' Bourbon Street, that's hard to believe.

No, the day after the Super Bowl is just another Monday, and for students on the University of Colorado at Boulder campus, it was an especially slick, sloppy and cold Monday at that.

"I definitely left for school late today. I didn't super party it up, but I stayed out 'til about midnight. The commute was terrible," grad student Laurie Trenary said.

Whether the blame lay with Sunday night's big game or with the fresh fallen snow, Monday was clearly an ideal day to hit the snooze button for many CU students.

Professor Moonhawk Kim described attendance for his 9 a.m. "Introduction to International Relations" course as "lower than usual." His class, which averaged 309 students last week, had 266 students show up, according to iClicker digital data Monday morning.

As to what caused the drop off, Kim couldn't say.

"I have no way of verifying. (The students) weren't there, so I can't ask them," Kim said.

Data collected by an online Harris interactive survey indicated that nearly 1.5 million Americans planned to call in sick to work the day after the Super Bowl in 2008. Another 4.4 million employees admitted to planning to go in later than usual.

With empty cubicles a likelihood for many businesses across the country, increased student absenteeism certainly was not surprising to CU students.

"My roommate missed his 10 o'clock. I would definitely blame the Super Bowl because his blinds were still closed," senior John Simmons said.

Even those who were unable to enjoy the game found themselves getting a late start Monday.

"I had a meeting at 7 p.m. (Sunday), so I didn't get to watch the whole game. I definitely was 20 minutes late to my 9 a.m. The snow didn't help," student Nathan Minatta said.
