Free Friday at Old Sturbridge Village, Berkshire Museum, Ecotarium, New Repertory Theatre

This Friday wraps up this summer's Free Fun Fridays, sponsored by the nonprofit Highland Street Foundation. This Friday the foundation will treat visitors to free admission to Old Sturbridge Village, Berkshire Museum in Pittsfield, Ecotarium in Worcester, and the New Repratory Theatre's 6 pm performance of "The Adventures of Huckleberry Finn'' at the Charles Mosesian Theater in the Arsenal Center for the Arts in Watertown. Highland Street began Free Fun Fridays a couple of years ago to celebrate the foundation’s 20th anniversary. The organization has donated more than $125 million to nonprofits to support projects benefiting children and families, primarily in Massachusetts and California, in education, housing, health care, environment, and the arts.
