well, I did the lower cave first but only to try and push that upper passage a little more than I did last time. I figure I can't make it through the opening into the little room at the end (me and my fat ass.) The upper cave is certainly better, but I saw so much TP this time! It was absolutely disgusting! The person I was with hurt her wrist at some point, so the side passage exploration was significantly less than I would have otherwise liked (but there was so much shit in there I don't think I would have wanted to go anyway!)
Has anyone ever checked out the cross tube in the lower part near the bottom end? (It comes in from the left as you're heading down the tube, and it's about 8-10 feet up)
