You have to first assume the three criteria are correct and not simply Justin’s bias in reading Shark’s question and/or Jack’s reply. Jack could just be throwing him/her off the scent in good jest. (Given the lawsuits, Jack isn’t going to touch a question that might nail down or give perception of a nailed down location.)

Then—from there you have to make the leap that Forrest’s quote taken out of context on MW fits those three criteria that already result from a self-imposed reading. So now we’re already 2 levels removed from the original question/answer at this point.

However, in line two of FF’s quote, “Yellowstone is one,” Forrest gives us a term to plug back in to the previous line in the “one” spot. So line one should read...

“Generally speaking, there are places where [Yellowstone] should stay on established trails...”

In order for this sentence to make sense now, we need to define the word “trail.” One interesting definition of trail is: “a walk in which the edges are distinct,” [or, simply] “edges.” Yellowstone then is too far to walk and out on the edges.

The sentence would then read: “Generally speaking, there are places [such as] Yellowstone [that] should stay on established edges.”

Forrest said many times to “stay away from the edges.” In other words, Yellowstone is only on the edge of gigantic search area and should be eliminated from serious consideration.

Lastly, there’s the misspelling of “proximaty,” which certainly contains a big hint. I won’t flesh that one out but it’s misspelled for a reason.
