Thanks for the offer. I won't be able to make it unless some money floods in, or a fellow Wizards' teleportation experiments bear fruit, as I live in the UK.
Both the potluck and the group craft ideas sound good to get people talking and interacting. Sometimes spontaneous rituals do arise. Many years ago I attended a Solstice and Equinox Group that used to meet at various ley line intersections and do a loosely structured ritual. Almost every time passers-by would stop to watch, and frequently join in and then come back to the shared meal - usually at a local village hall.
Just smiling at the thought there must be a few photograph albums out there now with pictures of these events. I can just hear the comments when they are shown to family and friends - possibly even on DVD - with the owners saying something along the lines of
"This is the walk through Kingley Vale we did back in 1987. Here are the thousands of years old Yew trees. Oh! and this is the Pagans we came across doing a ritual. Yes that's your Dad sweeping the way before them with a traditional Witches broom, that's your auntie Madge helping with the fire in that cauldron.
Ooh! These are some of the pictures of the meal back at the hall where we went afterwards - first time we realised veggie food wasn't all bland and lentils.." Terry Pratchett
would have had a field day. Come to think of it who's to say he might not have based some of his characters on a viewing of one of those albums? :->
