Eight people made it for the trip this year.  The water level in the cave was at least 10 feet lower than it was two years ago.  That opened up areas that were inaccessible back then and we were able to see much more of the interior this time.  The guides pointed out all the artifacts left behind by the quarrying operations and any points of particular interest.  They were hard to understand at times because of the accoustics of the place, lots of echoes.  The squeeze corridor where one has to lay back in the boat and push yourself along with your hands on the ceiling seemed longer this time.  This passage is one place a long nose is a distinct disadvantage.  It was pleasantly cool in the cave, the water downright chilly.  I think all participants enjoyed the trip.  It is certainly an out of the ordinary experience.
