Swinger's Clubs in South Carolina

My wife (and I) would like to visit a Swinger's Club in South Carolina. There seem to be a few with good reputations. Has anyone here ever frequented the Anderson, Clinton, Columbia or Myrtle Beach clubs? We'd really like to start with no pressure, gentle introduction with a host couple. We're more voyeur inclined that actually participating fully our first time out.

If you find one. Please let me know. (An avid swinger, here!)

Not sure of any "public" swinger clubs in the Upstate, I only know of a "private" club held at a residence.
