Did he make the clues first and then found the location or did he know of the location and then made the clues?
Another thing also, First I believe I know where warm waters hault. That being said. To try and offer a little help before I start my own topic, I'd like to make a suggestion to everyone .. call it a prelude to what I'll tell you later in my topic. A help if you will before hand.
... "where warm waters hault"..
What is "warm" water? It's hot and cold water.
Now ask yourselves, where is hot and cold water? They are separated. One is HOT and One is COLD. Now ask yourselves again, WHERE IS THAT?
Make a list of all the possibilities and I'll bet it will be in your list. (now what will you do with your list)
It's interesting - I started this "adventure" with my son (he's 12), when he asked to do the chase a couple of months ago. His initial thought for 'where warm waters halt' - the bathtub, the sink, the drain plug, into a pot before cooking....each of those has geologic equivalents - basins, sinks, plugs, kettles, potholes, etc.
He has his own "solve"....it's me that's confusing myself looking for something that may, in fact, be staring me right in the face!
