We got the back side of the barn done! Replaced the upper vent with a window and re-attached the rain spouting. The only mishap was one nail out of the nail gun missed a board, went inside the barn, where it ricocheted off a wine barrel and shattered a window pane from the inside. But we got it fixed and all looks good now.
Now we will work on taking the old silo down!
Sadly there will be a bit of break in the barn progress, as we are waiting for warmer weather to stain the remaining boards for the front of the barn. Hoping for May to get this done.
