Walls are going up

Tom took this picture on the way to work this morning. From what I can tell, it appears that the external wall structure is nearly complete.  This picture is taken from the north side, looking at the front of the house.  The front door will be in the middle – you might be able to see the small front stoop mostly hiding behind the pile of 2×4’s.  On the right, you can see the large opening for the garage.  On the left is one of the guest bedrooms.  I haven’t yet seen any pre-made trusses.  I wonder if they will deliver those or make them on-site. Also, will the plywood be put on the walls first or will the roof go on next?  Stay tuned!
