Perhaps someone enterprising could set a date and have a meetup/munch at an SF kink cafe called 'Wicked Grounds'.
Contact the Management , who would be quite happy with this- it's the sort of genre they host anyway. And KT and I both think the food and atmosphere are great!
Unfortunately we don't live in San Fran so cannot get the event going ourselves.
Dunno what's going on now, but there used to be a really active Gathering community in the south bay. Might want to check the Gatherings section and see if it's still around.
