 is a good question because now you're starting to say, well, if I have to replace something more frequently, and even though it came from a more sustainable source, is that sustainable? So in those kinds of discussions, we both learned a lot about the process, and I think they became a better organization for it. And ironically, I just met with one of their individuals the other day, and they have now done a number of gold lead buildings around this area. So I like to say maybe we were responsible for helping kind of move them along in this continuum.
