When we got home, neither the house nor the trailer nor the Rolling Stone were frozen, although with the trailer thermometer reading 4°C, it was a near thing. We poured more RV anti-freeze into the Rolling Stone. I got the fire going in the house, where it was 10°C. We went to bed early as it was about the only way to stay warm and besides, we were tired from all the driving.
Today was deliberately a day of rest. I slept in very late and mainly just read and caught up on e-mail and such while stoking the fireplace and keeping the fans running to try and get the front part of the house back up to a more comfortable temperature. Day Jobbe looms tomorrow, after all.
