I think the first paragraph hints at drawing a circle centered on the middle em dash. Middle is the middle word in the paragraph and there are lots of circle references. "brimmed to the rim" "circular route" etc

When you draw a circle that is 5 1/2 lines tall (matching the 5 1/2 years old) it intersects 2 x's in the paragraph.

Using a map overlay with the Xs on Houston and New Orleans, the center of that circle is Arkansas.

Then the 16 capital letters may hint at drawing two lines that intersect in Missouri.

HoB-nail box

HoB = Home of Brown, but in JCB's poem its what once way Brown. I think that might be Olathe, CO which used to be called Brown, CO

It could be in the nearby black canyon of the Gunnison, with the Gunnison river being the golden bending stream as its known for gold mining and gold medal fishing.

Thats the core of the theory. I put some more thoughts together in a very long rambling video if you are interested: https://www.youtube.com/watch?v=BXrp3pfprMU
