First, Evercat -- your avatar is SO cool!
Now onto the questions ... I think they'd do something TOTALLY different. Like, not religious at all, but a celebration of love.
Picture this: A bonfire at a beach (they are in CA, after all). Everyone shows up in thin material, light colors ... and everyone has to bring a quote or song .. or something .. that, to them, defines love. It's about sharing their love ... and in turn, having others share love with them.
Make sense?
Oh, and lots of flowers - maybe leis or something.
Yeah. Okay, that's my idea.
