One of the comments you made was about a solar energy program for domestic builds and commercial builds. One of the frustrations I've seen is that we've never started at the bottom of that equation. We always start at the top. You go to China, where there's immense building going on and solar energy wherever you look, and they're retrofitting the roofs on all their buildings so they're on the right angle.
Have you folks done anything to talk to our builders so that you build the pitch of your house facing the right direction and you get southern exposure and also so it's the right pitch already when you perhaps put solar panels on that roof at some point? That's so, number one, it really isn't a major retrofit, and number two, it's pleasing to the eye, if you will.
