Murphy,
I am in Oklahoma right now. Don't believe I have ever been to Frog Tanks.
I tried to form my questions in such a way that no one would feel threatened by giving an opinion. That, obviously did not work.
It seems to me, that you are going about this in reverse. Trying to figure out which of the Military Trails from Dr. Glover's book is the "LDM' trail, will not work.
The best way, in my opinion, is to focus on an area using all of the other clues, and then look around for a Military Trail. It may or may not be shown in Dr. Glover's book. I would just guess that there may be a few such trails that are not shown on that particular map.
The "Military Trail" clue should not be at the top of the food chain, once again, in my opinion. I believe it comes from a questionable source.
I was really trying to see how many people thought it was important. Not just as a possible clue, but in their own search. I am fairly certain I have found THE Military Trail, assuming the clue is factual as opposed to pure fiction, but as with all things Dutchman, it could be coincidence. Many other stories and clues brought me to my own conclusion, as to the location of the general area of the LDM.
I don't believe there is anything left at the location, but it would be interesting to take a look. I will leave that to my partner.
Respectfully,
Joe
