Here again, Randall Carlson, and we got with us tonight our good friend Chuck Kazina. Been on multiple tours with us. Is a planetary scientist with a specialization in geology. Had a lot of involvement with environmental regulation, and he's going to give us all kinds of feedback and perspective on some of Randall's recent articles in the newsletter. If you're not getting the newsletter, sign up for those. And Randall, we got a lot of different directions we could go. A lot of things in the news. Lots of new papers about mega floods. About asteroids whizzing by. Tours coming up. Yeah, so multiple directions, and welcome, Chuck. Good to have you, buddy. Yeah, thanks. Great to be here.
