Monica DeSalvo’s series “A Bus Tour in the Woods” was influenced by a recent trip to Greece for an art-making workshop on the island of Skopelos. There she found a path toward creating works inspired by one of the hallucinations her late father, Sal, had during his waning health and waxing dementia. The free exhibition can be viewed at the Hopkinton Center for the Arts’ Lotvin Family Gallery Mondays through Fridays from 9 a.m.-6 p.m. and Saturdays and Sundays from 9 a.m.-2 p.m. from Aug. 29-Sept. 29.
