So, in between jamming my finger on a crowbar and overstraining most of the muscles in my legs, I did manage to help Don get some demolition done on Sunday. We concentrated on the middle bedroom, and have now gotten it almost done. All that's left is the ceiling and most of the back wall, and we can move on to the back bedroom.
This weekend will probably be devoted solely to demolition (other than a brief break for me, to go to the crafting afternoon at Evelyn's!). As always, if you are feeling sledgehammery, you're more than welcome to come and help. If I get an actual confirmation of attendance by anyone other than me and Don by Friday afternoon, I'll arrange to cook dinner for whoever helps.
No photos of the progress yet; at this time of year I'm rarely home when there's enough daylight to go up and take pictures. I'll post some as soon as I get them.
