New roof vents

I removed the original vents and the light kits attached to them. They were nasty. One had a full bird's nest (or, maybe a rat's). The others had numerous wasp nests. Amazingly, all the fans still work. I am replacing them with Fantastic Fans. I hear these are the shiznit. They definitely look cool and their smoked, semi-transparent domes will help bring in light. No more light kit means I gain an extra 4 inches or so of headroom.
