We spent the day today doing electrical. I mounted the electrical boxes (the blue things in the pictures below) for the lights onto 2x4s, which I then mounted between the i-joists in the ceiling.
It was fun, and even Brad remarked that my mood was much better. :)
Brad is running wire all over the house, including many network cables. As you might guess, in addition to wireless, we will have many network connections all over the house. It is a great deal of fun to put stuff wherever we want it and to think about what it will all be like when it is done.
