I love to read about stories like this!  I just makes you want to put on your boots and get out hiking.  You just don't know what you are going to find.  If you can-- click on the video.  INCREDIBLE---  This summer I went hiking with a friend WAY UP a mountain.  At the top of the mountain was a very short cave.  We did not do it because I am not a cave explorer and we did not have any rope but if we were to get on our belly and crawl in the cave it  takes a drop down 50-60 feet (some say).  I really want to go back with my brother who knows how to repel and do some exploring.
