(Re open container suspension) A few years ago I paid a $280 fine for walking an open beer across the street in Athens. To this article's point I think the cops pick and choose as to where they may be most effective at a given point in the day, the beer didn't have a label on it (I brewed it) and the cop may have thought it looked odd.
Although the town has stayed the same since my years in Athens, I do think there is an uptick in underage drinking in general, or at the least a larger movement to drinking harder spirits. Personally, I think there is a larger mention of liquor by name in today's music than there has been in the past and that plays a part.
