The overnight lows are supposed to be very low tonight in my area. We haven't put the storm windows up yet because it was too windy this weekend to do it safely. Think I'll head out to put them up really quickly in a few minutes. Are the rest of you turning down the thermostat this winter? I kept it at 67 during the day at 65 at night (we have a boiler and were told to leave it at the same temp 24/7). I'm going to drop it to 65/63 this winter. What are you doing?
