The Senior Graduation Party occurred today. In addition to a free Alumni T-shirt and food (for up to 500 people, but it seemed like it fed a lot less than that), there were a few games as well as raffle prizes (which of course appeared to be horribly rigged as two people won two raffle prizes.)
Note I had to resort to my cellphone camera for this image - it helps to bring a camera, but not if you forgot to put your SD chip back in.
What drew people in: Free beers. Two of them. Quoted by a student on the event page: "How could I say no?!" *(Note that I don't drink beers or any other alcoholic beverages myself)
