Yep, I'm a geek.
Under "normal" circumstances I'd be home dealing with this instead of Bob, but since he's out of work it doesn't make sense for me to take a vacation day just to watch them snake a thirty foot tube down my chimney [you all just stop thinking those things RIGHT NOW!]
I have instructed him to take pictures. He's also going to take advantage of the ladder being up to clean our top gutter. I feel kind of bad for the guys - I would imagine that at most homes they can do their jobs in peace. At our house, one or both of the homeowners is inevitably shinneying up the ladder after them to get stuff done on the roof. We're opportunistic like that.
I'm just too much of a control freak to be happy about the installation of a major system without my supervision. On the other hand, I did skip the installation of the air conditioning system, because the idea of someone drilling holes through the side of my house gives me palpatations.
At least they have good weather for mucking around on the roof. I wonder if I should install lightening rods?
