Where to find mooning buddies

I'm a guy in my 20s, and for as long as I can remember, I loved mooning. Granted, I'd find places I wouldn't be spotted, so I don't know if that's considered mooning, but flashing my bare ** in public spaces is what I mean, be it through windows or outside. I find it a thrill, however, I've always done it alone. I wanna find some friends who not only I can show my ** to, but who will go mooning with me. Is there like an online group for this sort of thing?
