Huzzah! The plumbing is done and functional! Today the framing crew came and replaced all the sub-floor that had to be pulled up to do the plumbing and wiring. Now it is much less treacherous for people who fall down a lot, like me. And better? It doesn't feel quite so arctic in here now that there are no direct passages into un-insulated attic.
We are go for insulation (Yay!) and dry walling. Very exciting!
