Join us for Free Friday Night Fun all summer, through August 31! Both museums will be open with free admission beginning at 4:30 p.m. Explore the museums at night and picnic under the stars with food from the Chef on Wheels grill—burgers, hotdogs, veggie burgers, pretzels, slushies and more. Donations for the Acton Food Pantry will be gratefully accepted. Sponsored by MathWorks and Middlesex Savings Bank, with additional support from Emerson Hospital.
