From Annie Tucker, whose home (and her husband David's) is on the left of this duplex:
When I was little and would draw a house, I'd draw a square and then a triangle on top for the roof. When a house is being built, the trusses are what make the triangle shape. Today the trusses are being put up on our unit. Now we can see the beginning of the walls AND the roof! Very exciting!!
And on Wednesday, more progress:
