By Larry ChaseThe temperature’s about to rise on this large-scale “thermometer” mounted in front of The Andover Community Hub headquarters at 157 Main Street in Andover and showing the Hub’s progress toward its goal of raising $100,000 for capital improvements to the building, Andover’s old town hall. The photo, taken on February 14, shows gifts and grants received, at the time totaling about $35,000. By March 1, the amount is expected to climb to about $50,000. Photo: Susan Chase
