Central MA here. Haven't had a fire yet, but possibly this week. It's been dipping into the low 40s overnight several nights, but the days have been sunny and 50s-60s...until the weekend. Still, the house seems to hold heat pretty well. Now that the sun has been hiding I expect that to change. Had 65F this morning in the bedroom. Still not bad but starting to "make the case" for a "small fire" lol!
