Cave seems like a good idea. People probably camp in those, right? Or maybe it's like an art installation cave that was pitched as some intersection of art and technology, like usual. Though it is terribly dark here. Not in the night sense, but more in the only-lit-up-by-your-tiny-porta-potty-trip-flashlight sense. Oh, and speaking of, you just found a giant hole with someone crying at the bottom of it that you can’t see, sounds like.
