Today is our block party, and they are not playing: donations were solicited for a "bouncer" (read: bouncy castle.) Wowsers! (Technically, I suppose they are playing, but you know what I mean.)
Last year, I took the opportunity to essay a baroque and slightly vile mix-based pistachio-chocolate bundt, and it didn't exactly move. Now, since I feel my honor is on the line (and I really would like to contribute something people will like) I am going with the most tried of favorites: Rice Krispie Treats (even though I hate them) and chocolate cupcakes with ganache, weather permitting.
(As M said, "the hippies, in lieu of money or food, will probably be providing music.")
