Considering our need for organization, wouldn't it be easier just to pencil in a whole weekend for a Spring Fling?
One problem would be finding a place to put everyone where access could be controlled and alcohol legally served. Ever since Harvard Real Estate banished kegs from Memorial Hall, there has been no available enclosed space large enough to accomodate all undergraduates. One possible solution is to cordon off the MAC Quad for an afternoon, as is done for "Riverfest" in the fall.
The more significant obstacle is the College's foolish pretense that the house system is capable of providing an adequate social life. Thus, the undergraduate population is divided into tiny portions for Thropstock, Quincy Spring Weekend, Quadfest, etc.
WHY is it so important that the entire College party together? The answer is guilt. With small groups having fun at different times, you can never fully enjoy yourself. You know that somewhere out there, there is a person who is studying, and you're not; and that person will get a better grade than you, get into a better law/medical/business school than you, get a higher paying job and have a better-looking spouse.
But if everyone lets loose together, celebrating the almost-end of the semester, the fun is remarkably guilt-free. At Harvard, a little positive peer pressure can go a long way.
With some energetic organizers, there is no reason why a Spring Fling would be unsuccessful at Harvard. OK, so we're all uptight and the administration seems determined to stop us from enjoying ourselves. But other than that, there's no reason why Harvard students can't party in groups larger than a SONG meeting.
The barbeque behind Sever was...nice. Quadfest was...in the Quad. The raft race is... cancelled. We need more. We need a weekend set aside for pure fun, games and general debauchery. Even Harvard students are not above a little frivolousness every once in a while.
