What kind of festival should we have?

Well, Rubefest was almost a reality except for one thing: beer. I had a great space (outside at Jamaican Jerk Hut) but I couldn't charge people to attend if I had booze (it's a BYO), and I didn't have enough time to get kegs donated. But I still think we could have a great event, maybe in July, with music, food, and booze, but we need something Phillycentric and/or absurd to celebrate. Any ideas?
