Well as a confirmed naturist, must say I do enjoy reading all the banter on here once a thread on the subject gets underway - it's certainly entertaining.
I think there are already plenty of posts elsewhere in the naturist section on MHF, where folk have explained why they enjoy the lifestyle. Some have even alluded to their personal pleasure in this thread.
Naturists are just ordinary people choosing not to wear clothes when the weather and circumstances are appropriate. Their activities are no different from what many people choose to do in their leisure time, other than the dress code.
What better way to 'get back to nature' than using the van to visit places and events. Nudefest, happens to be a successful annual summer gathering organised by British Naturism for members (and non-members) of a similar persuasion, to get together, socialise and have fun.
As an aside, I just got hold of the English-language edition of a 2013 naturist holiday guide published in France, which offers 816 destinations to stay. Seems the French are equally enlightened about naturism as they are about motorhoming.
PS Sorry barryd, no tutting or rolling of eyes, just smiling.
