Wilda Dunham, left, of Sumner and Joyce DeWildt of Buckfield said that despite filling gaps, squirrels continue to get inside and knock insulation down from the ceiling at the Buckfield-Sumner Swap Shop in Buckfield. Volunteers run portable heaters to stay warm, but with a steady flow of traffic coming through the door, the temperature hovered around 50 degrees inside on Wednesday. Dunham and DeWildt keep track of the mice they catch on their chart labeled “mouse kills,” but they have not figured out a way to stop the squirrels. The swap shop celebrated its 10 year anniversary in 2018. (Sun Journal photo by Daryn Slover)
