Putting in the upper yard, part one

Well, after a lot of prep work, the upper yeard has been hung from the ceiling. We put up the right side of the yard ladder first, then proceeded to work our way around the room. We had a crew of six of us and in 2 hours we hung three panels of the loop, including the ladder. In the last shot you can see we came up with a gauge that measured the height of the yard off the base loop that has yet to be built. It is actually 80 inches from the floor. It contains 6 tracks.
