I also got another window open in the carriage house bedroom. That room still smells fairly vile, so it needs another few passes, clearly. The open window will help. It doesn't have glass in it, but it does have a storm window on it. It had been stuffed with R-13 fiberglass insulation and covered with Visqueen.
That was the sum total of today's progress. I'm busy with paying work this week; don't expect much.
