What are your views on them (groups like the AANR in the US or BN in the UK). Campaigning for all nudists, or a kind of organisation just for clubs and nude holiday and camp sites?
You should have noted that in the USA, there are two national organizations. It's too bad that you missed the Naturist Society, because that has the alternative focus that you mentioned--"campaigning for all nudists"--paticularly in public places. It dates back to the "Free beach movement" which was a kind of hangover from the hippie era, so it's perfectly in line with Hipforums! http://www.naturistsociety.com/
