The Main Street Farmers Market will wrap up its 10th season with a final regular weekly market Saturday morning and then put a bow on it Tuesday night with Shopping by Lantern Light. As usual, the Saturday market will be open from 9 a.m. until 12:30 p.m. in Charlie Olliff Square, off East Main Street behind Sea Island Bank. “We have about an equal number of produce vendors and farmers and food purveyors with prepared foods, and then we have a smaller number of craft vendors because we’re primarily a food market, but we do have a few of those as well,” said Market Manager Melanie Sparrow, describing how Saturday markets shape up all season.
