Renowned for exploring industrial landscapes and abandoned architecture, Christopher Payne delved into the forgotten corners of America's built environment for projects like Asylum and North Brother Island, to the latest, most advanced technologies that build the country now in his latest book, Made In America. What goes on in a shipyard that builds nuclear submarines? Chris has seen and photographed it.

From the mailbag, photographing a stranger changes Steve Reeves' outlook on life, Jeremy Durham on 'what we do,' Neil Ford is pondering the question, 'why post on social media,' and Michael Mixon is coming out of a creative lull, though has some words of quiet genius when it comes to why we make pictures. Plus it's the last call for those joining in with this month's assignment.

Links to all guests and features will be on the showpage, my sincere thanks to MPB.com who sponsor this show and the Extra Milers without whom we wouldn't be walking each week.
