An early alarm this morning, then out the door at just after 5.30 to get the train from Wolverton to work. It was very frosty. The big question of the day was whether the fire would still be in by the time I got back, some fourteen hours later. I'd piled plenty of coal in the stove before I left, and almost closed the lower vent -- and it worked, as it was still going. I didn't feel too bad about putting the Eberspacher on for an hour, as the neighbouring boat was running its engine. Tomorrow's forecast has improved considerably -- unless that also means the canal is frozen, which would be a problem.
