On the weekend of 6/2-3, with more rain threatening, we began putting the frame of the upper section of the first building together and constructing the roof trusses, and installed the wheels and the track on the first building.
During the following week, the rest of the roof truss parts were cut, and the hardware to hold down the roof (in the event of strong winds) was installed in the first building.
On the weekend of 6/9-10, the roof trusses were finished and added to the first building. The upper frame of the second building was built and the wheels were added, and then the trusses were attached.
