Checking it out doesn't make you a bad person or any less a nudist than you are. There are other places that have opened their doors to the swinger clientel and although we wouldn't visit ALL the time, we'd still like to visit because they are very nice places...ie Caliente Resort.
I think knowing what you might encounter or at least knowing what to possibly expect is better than going someplace and not knowing and have something happen you weren't expecting.
If we had the opportunity to visit Riverside Ranch, we'd probably do so and decide for ourselves if it's as bad as everyone says it is. If it makes you uncomfortable.....you can always leave, that's what we'd do. But if that particular group isn't there that day, it may turn out to be a good day and you'll be glad you at least visited.
If you do decide, gives us a report.
Take care and good luck with your decision.
