I started a munch for local kinksters in my area.
I created an event on a website I frequent - and then showed up.
I set up in a local bar - there's a back area that's somewhat secluded - and we've met there 2nd Sunday of every month for the last 4 or 5 months.
Attendance has been as little as me, to as many as 8? I think was the most.
Its been fun, and something I'll continue to do
