We're not sure exactly what happened, but there's no heat in the living room. The breaker kicked out and we can't turn it back on. We brought portable heaters up from the basement and got the temp from 62 to 68 F. The girls are back in bed, toasting on the electric blanket. Electrician is coming tomorrow afternoon to see what happened; he said he'd come in today, but we don't want to drag him out on a Sunday. We'll survive. We're thinking it's probably the thermostat. (Gee, guess I'll have to bake something to turn the oven on!)
