Now about the cache. Terrain is due to final leg of cache only.
Did you ever play Battleship when you were a kid? Well, this is my
version of Geocaching Battleship. Unlike other puzzles, you will
start at the posted coords and just follow instructions.
I was never very accurate at knowing True or Magnetic North,
East, South, or West so as you will soon find out, the directions
may cause you to use your imagination some. But I have no doubt
that you will eventually get it. You will either get a hit or a
miss.
You will know when you have found the sunken
cache.
