Fenix brought up some page turns, so I listened. And then we listened some more...
Starting at the beginning of the audio, there are page turns that identify words.
These words yield ANDREW in diagonal acrostic.
At 2:38, there are alternating shovels and coins that identify words. These words seem to yield SPLIT. This time, the diagonal acrostic reads up instead of down. The "S" is separated from the rest by quite some time, and I believe this confirms the clue by having the word SPLIT be literally split.
Once the poem begins, there are some doubled words that I've mentioned previously. These are also identified by a falcon shriek on each. These words yield CENTER in the same diagonal acrostic.
At 4:48 the music briefly starts up again to highlight:
Without bounds, In the Spring, Thy Namesake’s Young.”
The reader's phrasing screams, "Word play! A three part word!"
I toiled on this for some time and failed miserably. Luckily, we had an extremely astute North Dakotan, Chad Porta, in our corner to pin it down. Free, May, Son. So, FREEMASON. Know any famous ones?
I already feel confident this thing resolves where a dozen is more: Baker's Bluff on the Jackson Branch in the Middle Tennessee region. Home of the Highland Rim and Grand Ole Opry.
It's possible these words mean something else... but they're pretty convenient for a spot that is already heavily confirmed by another presidential first name and some mile markers, wouldn't you say?
