In the summer of 2006, film director Mike Leonard joined the 251 Club, an organization dedicated to visiting all the towns and cities in Vermont. With his two best friends in tow, Leonard traveled the state interviewing locals and filming some of Vermont’s most celebrated places. A decade later, Leonard returned to some of the same places and re-interviewed some of the same people he’d met 12 years before. He witnessed how Vermont has changed, how it has stayed the same and, ultimately, how the experience shaped his identity forever. In “One Town at a Time” Leonard shares this experience as he explores Vermont’s 251 towns and cities. The film will be screened at Barre’s Old Labor Hall, 46 Granite St., Sunday, Sept. 8 at 7 p.m. Suggested donation is $5. oldlaborhall.org. The film combines footage from 2006 with contemporary footage to reflect on Vermont’s changing cultural and physical landscape. It’s diverse voices include former Gov. Jim Douglas and Ben & Jerry’s co-founder Jerry Greenfield, as well as 251 Club members of all kinds. The film was recently screened at the Middlebury New Filmmakers Festival to great fanfare. The Labor Hall showing will be followed by a question and answer session with Leonard.
