Dr. Chris Jackson's just back from his volcano tour with the BBC (well, like, as in a few weeks ago. But that's pretty timely for us, right?). Having Dr. Jackson on the show is always an honor, and we're pleased to get an "exclusive" (ignoring the whole BBC thing) from him about his time in the DNR. Watch the video below to see Chris wearing shoes (Re: UR Sock Sessions), pictures from his trip, and Matt looking flustered after joining the episode 15 minutes late. The show notes are here, and the pictures we're discussing are here.
