Here is the 'other' valley beam on the other side of the house. That light spot is where the wood had been compressed from the previous brace (you guessed it, a 2x4 and a couple nails). This will now have a shiny new 4x4 brace (which John is holding in this picture). In addition, that big center column will be supporting a lot of the weight previously supported by this brace.
Here we see the worst day of the job for John. He is putting brackets at the base of all the rafters to better attach them to the walls. If you look closely, you can see the metal bracket on the rafter. One of those for every rafter in the house. Fun fun fun.
And finally, here is what is NOT happening in my attic!
Up the street, someone else was having insulation blown into or sucked out of thier attic, and this happened: Yikes!
