Kind of been wondering about this, the Burning Man event seems to attract a lot of leftists, but attracts my interest as it seems to also attract artists and artistic expression, maybe a kind of environmentalism, I don't know. Their main celebration seems to have been a repackaging of the pagan event of burning a wicker man, they burn a big effigy to end the event.
It's kind of ambiguous about being pagan or nonreligious or whatever but I think there are probably plenty of objectionable things that take place that "conservatives" or "Christians" might want to steer clear of. But, I think possibly there are good things that might be adapted in to some alternative new event or incorporated in to existing events.
Any idea about "Christian conservative" alternatives to Burning Man?
Why not a gigantic tent revival?
