Last night I felt like I made a bit more progress. I started with a mostly laid out top and bottom plate and turned it into a 12' section. This makes the fourth section I've completed.
The first two go on the overhead door end of the garage, numer three is a 6' section on the north wall that joins one on the garage door end. This one extends down the same (north) side. This makes halfway down that side. Tonight I am going to try to get three more sill plates measured and marked off so I can continue for the next several days while we have rain forecasted.
While it looks like this section might not make it out the door, I have measured and there is almost 8" to spare.
