My chapter had an event that we called AKAday. It was a combination of a campus wide cook out and "old school" field day events (y'all remember that?) such as sack races, the balloon toss, tug of war (we kicked some '06 booty
), and some others. We also set up a volleyball net and had that going on. It was something that the entire campus was able to participate in and everyone had a great time. This was something that we did during AKA week though.
