 Well, it doesn't sound like Jim's there. He's not there, so we'll move on. Anyway, he wanted to ask a question about cleaning concrete. We had a couple of them yesterday. His question was about graffiti on concrete, how to clean it off. Oh, okay. Looks like he's back. Oh, he's back. Okay. One of the things we get when concrete gets a little bit older, we start having efflorescence, which is that white salt. There is an efflorescent cleaner that'll take care of that project. Jim, are you there?
