The Mr and I have attended a few meet n greets. They've all been pretty different. There's a couple we know who says Tennessee meet n greets are quieter, with comfry seating areas to talk, and an area to watch porn. Ours here are loud boisterious get togethers, with music etc.
There are several area groups that have meet and greets every weekend. Some happen in bars, resteraunts, and dance clubs. The number is so large (140-400) that it is a complete take over and the place is warned that the swingers are coming in. We do also have some swinger clubs that people can attend. There are several people that post that they have house parties. People that attend house parties can be from 20-60 people at least.
