The light of a diver breaking the darkness of the night and depth of the sea
You can't appreaciate how lonely darkeness is until you sink 50 feet below the surface of the water at nigth and turn off your light. While the analogy of a cave could be used the sense of fear that sweeps thru your body is nothing like that experienced in the darkness of a cave. In water you don't have gravity to tell you what way is up, you are covered by a layer of unbreathable substance that wants to find a way into your dive mask, the currents pull your body to and fro, no - give me a cave without light any day of the week. That said it was a fantastic dive and I'll do again with experienced people. the colours and life at night are just incredible. It was also very special to be diving on the night of winter solstice the longest night of the year.
