This weekend's Cherry Blossom Festival at the Brooklyn Botanic Garden should draw plenty of carousers to Kings County. Flatbush Farm, about a twenty minute walk from the festivities, hopes to accommodate the spillover by hosting its own spring celebration, a weekend-long backyard barbecue in its sprawling outdoor courtyard (April 28th and 29th from 2–6 PM; 718-622-FARM). The menu will feature everything from grilled clams and pulled pork sandwiches to Sixpoint Craft Ales and Orange Blossom cocktails (Nigori sake with Cointreau and orange blossom water), and a DJ will spin soul, bluegrass and jazz.
