Your project is coming along nicely. Speaking of rhubarb cake, I have been on a steady diet of rhubarb cake and rhubarb/strawberry jam for the last week or so. My wife has a small patch of it and has been making good use of it. Also, our neighbor lady was in a bad car wreck this winter and isn't recovered enough yet mow her lawn. We have been doing it for her. She also has a rhubarb patch and has given us rhubarb, cake and jam. Oh..... and a huge bottle of wine. Anyway, I also know about sore knees. Sometimes I'm smart enough to use the set of knee pads that I have. They really help.
