As far as I know, there are no high IQ societies where you'd meet people of the sort you want and that allow for exceptions to their admission requirements. However, a lot of high IQ societies like Mensa will take IQ proxy tests such as older versions of the SAT (if you took it a long time ago) b/c they aligned well with IQ. You could also just go the route of taking the Mensa admission test and see if you make it on that.
Not that Mensa is the only high IQ society, but they are one of the larger ones and, thus, more likely to have active groups in most areas. They are also offering their home test for free in January, which would give you an idea as to whether you'd pass the "real" entry test.
