Revisit, new locations for El Camino Real de los Tejas NHT in Louisiana

The trail winds amongst several states, as per the map:

I had previously gotten perhaps three locations for this trail in Texas visits, I did not remember that the trail started in Louisiana, as part of a long trail to Mexico City: 

I got stamps from two locations during my visit to the Cane River Creole NHP today:

First stop was the Natchitoches City Visitor Center, where there were actually three stamps,

Also got a stamp at the Oakland Plantation store unit of the Cane River Creole NHP.
