The New Hampshire Antiquarian Society has cleaned out its attic for the summer exhibit. This June, the second floor is dedicated to all the cool Hopkinton-related things society members have donated over the years, including the old Hopkinton post office window, a carousel horse, portraits of a local family by a well-known itinerant painter, and an old fire engine pumper used in town in 1811. (Never seen a hose made of leather and brass studs? Here’s your chance!) The museum is located on 300 Main Street, and is open Thursday, Friday and Saturday.
