Hi. I live in Louisiana and grew up on the el camino reale (Hwy 84). It extends from Natchitoches on the red river to Natchez, Mississippi which is on the Mississippi river. This last stretch of trail I haven't seen posted on any of the maps in this thread. There is a sign, posted by the state very close to where I grew up, that recoginizes this historic trail. From the Mississippi river you could smuggle goods/treasure north, south to New Orleans and the gulf of Mexico, or east.
I also found Sandy1 posts very informative. I have followed bent trees/limbs leading to carving sites that have been reworked over the years, just like out west. Some of the carvings on the old beech trees are basically illegible because of age. I also had one site that after visiting it a few times, had a new carving show up on a tree. Exactly like Sandy1 mentions in one of his posts. Not long after a house was built nearby, so I haven't went back. I have seen the bent trees/limbs all over this state and many pictures here on t net that look almost identical to what I see around here. Btw, now I live on Hwy. 80, also known as the Dixie Overland Highway. This was the first highway that ran all the way from the east coast to the west coast in the early 20's- 30's. I can't say it's all KGC for sure around here, but I do know whatever orginazation we are dealing with, they were marking trees in my area at least into the 1980's or so. Of course, there are treasure stories, both on Hwy 84 and Hwy 80 that came out around the same time as the rest of the country. When I started posting a few years ago, about bent trees/limbs in my area, some of the best ones have been removed/cut. Odd to say the least.
I almost forgot to mention Poverty Point is about 50 miles east of me and Watson Brake is about 15 miles away. Both these sites are located on the east/west line that Hwy. 80/ Interstate 20 follow today.
