Updated 7/3/2018:
It's been a while since I reported any progress. That's because there hasn't been any. Instead I discovered a couple of problems that I am closing to fixing.
1) I misread my plan for the Staging Area and built a table that is a bit too wide. I will cut that to size and re-install shortly.
2) I realized the backdrop that goes on the long wall is 2' 9" too short. I am working on a solution with the backdrop maker.
Neither of these errors are anything but speed bumps.
