Ahh college life. My DS got a drinking ticket the first week he was in college in Kenosha WI. The $25 dollar fine actually appeared on his monthly fee statement.
The second ticket he got was after he transfered out of hell and to a State University in Illinois. This time he was of age and broke the law by drinking on public property. He had a beer in his hand one evening was taking a garbage bag to the alley to put into the garbage can, so not walking around but stepped 2 feet onto public property from the backyard of his house. $575 including court fees. He couldn't just pay it, it was a MUST APPEAR.
My opinion is likely the same as the girls class. It isn't so much about the drinking, it is about the schools and college towns revenue building on the backs of students. They certainly pass out enough liquor licences.
At U of I they celebrate UnOfficial (St. Patricks day.) The campus has around 35,000 students. On UnOfficial they have maybe 80,000. My DS would always go over to U of I for UnOfficial. The drinking starts by the latest dawn on Friday morning. Students often dress in allaborate costumes that match. The Vikings pack ran through my DD 8am class one year, another cheerleaders (guys), I could go on but it is a fun google. At U of I students can go to the bar at 19 just so the don't drink. Yeah right. They do bar busts and make thousands of dollars a month. Why make it OK for a 19 to enter if you want to stop underaged?
