Thank goodness for outside sources otherwise i'd never post anything. From slyn:

Here's the naked truth about nude recreation: The people who practice it aren't getting any younger.

To draw 20- and 30-somethings, nudist groups and camps are trying everything from deep discounts on membership fees to a young ambassador program that encourages college and graduate students to talk to their peers about having fun in the buff.

...
No one is quite sure why nudity, at least the organized version promoted by the AANR and similar groups, is such a tough sell for younger people.

"I think people think that we're all hippies," said Laura Groezinger, 22, of Billerica, Mass., who grew up visiting Solair with her family. "Other people, I don't know the right way to say this, but they think it's more sexual, kind of. They don't understand just the being free with your body and being comfortable."

...
"I hope to get the word out to younger people that hey, it is OK, and here's a safe place to be, a very accepting place," Maguire said. "Unlike any other place in life, people actually look at you when they talk to you."

They're talking to you. So, all you under-40s out there, go and be free with your body....and stuff. Just not in my house.
