I definitely look forward to seeing (maybe participating?) in a version of this that's a little more polished.
I think it is possible to address logistical issues beforehand, maybe *start* outside the trees, have a brief intro where you talk matter of factly about being careful walking into and out of the grove, and then transition into "sacred space mode" walking silently into the trees. Then, when you walk back out, you've practiced doing that.
I'd be interested in exploring a version of this where you make the transition from "inside the trees" to "out looking at the bay" during the second verse of
Endless Lights. (Maybe bring high powered flashlights/lasers to point up into the sky during the third chorus?)
For a small version of this event, consider having a requirement be that people try hard to actually have all the songs memorized beforehand (this actually could make for a reasonable way to make an event like this public without getting too huge, with a barrier-to-entry that is totally reasonable). If the songs are memorized then you don't need lighting.
