Local nonprofit Greenspace will present a film festival at the State Theater in Elizabethtown, which will feature “A Community Conservation Effort,” a film about Greenspace’s mission and history. The film is a collaborative effort between several community members, including Sampley Brothers Productions and Greenspace board member Matt Deneen, who served as the writer, narrator and executive producer. The event also will feature several short award-winning conservation films from around the nation. Before the film screenings, a reception will take place from 6 to 7 p.m., featuring vendors, light fare and a cash bar.
