We passed a crucial point on the ceiling, and reached a new one. There is a hump on the ridge line of the old beer hall roof (see picture below), which we need to get passed, but I already have an idea.
But this has to wait, because tomorrow it is supposed to be warm, almost 40°F, in comparison to the last two weeks, that feels like summer. This won't mean that we take a day off, but that I will be able to pour some cement over the conduit from the new electric meter box into the house. The inspector wants it this way, so we'll do it.
