Looking straight down from the top of the walls.

At right is a heavy stack of trusses ready to lay out.

It worked pretty easily.  Room for one to walk the middle of the building on top of interior walls while one on the deck helped slid the trusses across and into place.

Once temporarily in place we began setting bracing.  Fortunately we had great weather. 

The garage truss setting was a little more difficult, but not as high in the air, it wasn't very scary.
