Summertime is the best time to enjoy free entertainment in your local national park! The Johnson Girls will be performing maritime music in the garden area of New Bedford Whaling National Historical Park in downtown New Bedford on Thursday evening, August 9 from 6:30 to 7:30 PM as part of its Thursday evening summer concert series. Then, on Saturday, August 11 from 12 noon-2 PM, Liz LeValley will be demonstrating the art of scrimshaw in the garden, while Ruth and Abby, the 1850s ladies, offer hands-on crafts for children. The Saturday afternoon activities are part of the park’s Maritime Heritage series. The concerts and maritime crafts are offered free each week at the park during July and August.
