PROSPECT PARK AND BROOKLYN BRIDGE PARK Get your volunteer on at It’s My Park! Day, a citywide effort to give our parks some much deserved TLC. Gather at Lookout Hill in Prospect Park at 10am to pitch in and store up some good karma in advance of Halloween debauchery next weekend. Or, if you have short people in tow, head to Brooklyn Bridge Park for the Harvest Festival at Pier 6 from 10:30am to 1pm. The day includes a parade, face painting, plant potting, pumpkin carving and a performance from the Deedle Deedle Dees.
