I plan to be at the Hatch Shell by 5:30 tomorrow (movie starts around sunset). I'm bringing hummus and pita, with enough to share. If other people want to bring food to share, that would be fine, too, but it's not required (and I'm not sure how I'd be sharing with mobs of people I don't know, since I want to make sure there's enough to share with people I do know).
I'm bringing majes's tarps and claiming some space. If other people want to bring blankets, though, that would probably be useful.
