My memory is that on the 2014 NEWT, Conxi Fornieles said she had been there the previous year, but the film she took then didn't satisfy her, and she came back with better equipment and more of a plan. She also brought a friend, another Spanish woman named Nelisa, to help her carry the gear and sometimes to act as camerawoman under Conxi's direction. You can see them both in the picture of the interview with Penny and Chris. Also on the trip in 2013, there was evidently the writer Mark Haskell Smith, who later came out with the book Naked at Lunch. NEWT2013 was one of his major sections, and he was very complimentary about Richard Foley and his attitude toward naturism.
I strolled into my favorite local library one day a year or so ago and casually looked along the shelf of new books, and there prominently displayed was Naked at Lunch. Well, I thought, this was obviously meant for me, so I checked it out and read it. It's a very interesting book, about how Mark Haskell Smith made a world tour around various nudist enterprises, from the "free range" to the "factory farmed". As I said, he could recognize places where someone was successfully putting naturism into practice, but he was also skeptical about some of the things he encountered. It's definitely worth reading if you can find a copy.
In response to Duane: in almost every case, other people we met on the trails were completely calm about nude hikers; some would make little jokes, or they'd just say hello in German or English, and walk on. That was true even if there were children present. But I do recall a couple of incidents where people were obviously uncomfortable. Even if they didn't make any negative comments, you could see them stiffen up and walk by with their gaze firmly set on some distant point. So it seems that even in German-speaking countries, there is some way to go to reach acceptance. Rich Foley's rule was "Stay covered up when you're on paved roads", and that seemed to be enough to keep us out of trouble.
