Not sure about the guy on the upper left, but the guy underneath him looks like he's attached to something.

Pete Sala said the installation of the crown truss was going to start in the northwest corner of the dome; the directional side close to the Falk school. If that is true, they are probably even further along in the process than they are here on what appears to be the northeast corner (closest to the Quad).
I can see lots of activity going on around the northwest corner. I am hoping someone can get a picture of what things look like over there. I suspect that will be the corner where we will first see actual pieces of the crown truss start getting put into place. I imagine the southwest corner, the one the camera is trained on, presents more challenges here as it is the corner that has the ticket offices, stadium control and the only large entrance for the building.
From Pete’s earlier comments, it sounds like the southeast corner might be the last to get done. He said they had to build another pad for the big crane that is shown here, currently located in the northeast corner, by the southeast corner so they can do work over there. I assume they can do the work for the southwest corner using Walt and his existing pad. Because of the hill, everything will have to be done higher from the ground, which has to make it harder, and they will have to be mindful of the extra activity in that corner. Makes sense to get the two easiest corners done first and hopefully have the process of building these support mechanisms well established before taking on the toughest (and incidentally most public) corner.
Still no white steel for the crown truss visible in the storage areas surrounding Walt. When that happens, things will really start to get interesting. It has to happen soon if they are going to complete the crown truss by the end of November, which I believe is the goal.
