85F. Mostly cloudy.
Really productive day! After learning, the hard way, that I should not (and could not) get a 4x8 sheet of plywood up on the roof by myself, I enlisted the help of @catsilo and Rachel, which turned out to be a lot easier, and a whole lot safer.
Bones, of course was on site to observe and supervise. He made sure that we took appropriate water breaks and always used 2 people to lift heavy objects.
