Giant Pumpkin Weekend @ New York Botanical Garden: Sat-Sun, October 26-27: 10am-6pm: Some may think mummies, werewolves, and other monsters are the highlight of the Halloween season, but nothing tops the monstrous, gargantuan gourds that headline Giant Pumpkin Weekend. Get up close and personal with some of the world’s largest pumpkins, meticulously cared for every year by elite growers and brought to NYBG in collaboration with the Great Pumpkin Commonwealth. (2900 Southern Pkwy, Bronx; www. Nybg.org)
