It was a good down to earth interview!
@ PhilipW a number of us here are already active Permolat members. I joined up over 10 years ago after shifting back to the West Coast after a long stint away. I've known Andrew B. since school days and we used to tramp a bit together starting in 1974 though we usually tramped with different friends or often solo in my case.
Back in 2012 I wrote a short promotional article about Permolat for this site. A lot has been accomplished since then and the concept has mushroomed. Here is a link to the 2012 piece. https://tramper.nz/7934/permolat-and-remote-huts/
