I like the idea of having a nude poker tournament. Not necessarily strip poker, but a lot of the younger generation is really in to Texas hold 'em so that could be a good option. Or maybe a nude casino night - I would definitely be there!
Would this resort be in Nevada.. or maybe on a river?

Where FYN has succeeded is that it hosts events. Events are, usually, cheaper than running resorts, & a event is usually less time consuming (maybe one night a week). I believe those are the keys to getting young people interested in naturism: it's cheap & doesn't consume a lot of time. That's where young naturists should advance to get others involved, IMO.
