This week we saw some framing, and the disappearance of the barn roof. That was put in place to divert water from the house during the predicted rain of last weekend. It was taken down early in the week and framing began.
Then today (Friday 12/21), the barn roof reappeared! Had some more rain come in, so here come the framers in the morning, and up goes half the roof. Really looks funny now, but it will keep the water out of the house (I hope!). 
The framers use nailguns which use braided nails made by a company called (and I'm not making this up) Amigo fasteners.
Kevin is home! Merry Christmas!
