"The Little White Schoolhouse on the Lake: a Hoot, Toot & Whistle for Vermont's Lost Valley" is a historical documentary about the southern Vermont town of Wilmington, its region, the Harriman Reservoir and the 1846 one-room schoolhouse on the shore that the Hawkins family bought in 1956. Now the summer home for my wife and me, the old house triggered our research: why was the house spared the farming valley's destruction for the 1924 building of the reservoir, also called Lake Whitingham? Was a factory town really drowned beneath the waters? How did the local economy evolve from farming to the railroad-and-industry era to today's tourism and service economy? This look at New England history was shown at the first International TV and Film Festival in Vermont in 2014, at the Brattleboro (Vt.) Museum and Art Center and at the Wilmington Historical Society.
