That's an interesting idea, thanks.
Still, what comes to mind is the original hippie scene, or perhaps folk music scene, which seemed to combine political activism with parties.
After all, if you are into consciousness expansion, a little bit of social/political awareness would not be out of place, would it?
I am not saying that one should become a radical - that, in my opinion, is often counterproductive, but if even a little bit of the energy generated at parties were channeled into some social issue, that, in my opinion, would be a lot.
Of course, I know about some of the green-living attempts, etc. That's a good thing, too.
Perhaps, some kind of ecovillage with psy parties held on the property would be a great thing.
