PHOTO BY JONI RENTZWhen it's summer on the North Fork then it's time for corn, tomatoes, peaches and plums. Nothing sums up summer better than fresh picked corn, left in the husk and grilled to perfection on the grill. And the best place to pick up a few dozen ears is at Seps in East Marion located on Rt 25. How 'bout them tomatoes? Well head over to Sang Lee for the best in heirloom varieties, located in Cutchogue on Rt 48. And if you're all the way out east then stop in at Lathams in Orient where tomatoes abound. Fill paper bags full of peaches and plums at Wickham's located in Cutchogue on Rt 25 for the best. Go to FARMSTANDS for locations.
