Good friends Martha Folsom (Arlington photographer --and mystery writer) and Mallory Rich (Sandgate pastel and oil painter) took weekly drives in Folsom's bright red Mini Cooper last summer and fall to explore backroads in southern Vermont. The result is a joint show of paintings and photographs at the Canfield Gallery in Arlington's Martha Canfield Library during the month of July. The opening reception is Saturday, July 8, from 3 to 5.
